The shield tunnels closely constructed near the foundations have an inevitable influence on the structures, even results in the large settlement or uplift of the structures.

The comparison of structural deformation of three different foundations is presented based on the field monitoring data.

Shield tunnelling parameters vary for the different types of foundations. For the long pile foundations, the recommended speed is 3 to 4 cm/min, the grouting pressure is about 0.3 MPa and the grouting rate ranges from 150 to 180.

The study based on the field monitoring data is rarely reported, especially the topic about the structural deformation of different types of the foundations.

Much of the housing stock in the UK is built on shrinkable clay soils, particularly in the south‐east of the country. When the moisture content of the clay soils is reduced the clay shrinks causing downward movement. This extraction of moisture from the clay may occur in a number of ways, but the main causes are either prolonged periods of dry weather (a combination of high average temperatures and low average rainfall) or tree roots extracting the moisture from the soil in close proximity to a property. The most extreme cases occur when a combination of the two causes is evident. Over the past few years the UK has seen some of the driest periods of weather on record which has meant that clay soils have not been able to replenish their seasonal moisture loss during the winter months. This has caused an increase in the number of cracks appearing in properties and a rise in the number of subsidence claims made against insurance companies. If climatologists are right about global warming, then subsidence damage has become an endemic hazard of home ownership. Prolonged periods of dry weather will continue to cause serious and very expensive damage to the country’s housing stock. The annual subsidence bill of £300 million can only be reduced by improving education and communication within the construction industry and encouraging house owners to look after their investments more carefully. This paper attempts to identify how the cost of subsidence damage can be reduced despite the changes in climate conditions.

Before beginning a detailed technical discussion on cracks it is necessary to put the subject into perspective and ask what ‘cracking’ means to a house owner or prospective house purchaser.

The dynamic response of the nuclear power plants (NPPs) with pile foundation reinforcement have not yet been systemically investigated in detail. Thus, there is an urgent need to improve evaluation methods for nonlithological foundation reinforcements, as this issue is bound to become an unavoidable task.

A nonlinear seismic wave input method is adopted to consider both a nonlinear viscoelastic artificial boundary and the nonlinear properties of the overburden layer soil. Subsequently, the effects of certain vital parameters on the structural response are analyzed.

A suitable range for the size of the overburden foundation is suggested. Then, when piles are used to reinforce the overburden foundation, the peak frequencies in the floor response spectra (FRS) in the horizontal direction becomes higher (38%). Finally, the Poisson ratio of the foundation soil has a significant influence on the FRS peak frequency in the vertical direction (reduce 35%–48%).

The quantifiable results are performed to demonstrate the seismic responses with respect to key design parameters, including foundational dimensions, the Poisson Ratio of the soil and the depth of the foundation. The results can help guide the development of seismic safety requirements for NPPs.

Highlights the importance, when undertaking survey work, of being aware of the potential damage to property from encroachment by tree roots. Reviews the general principles and legislation, citing specific cases of liability for damage, the question of foreseeability, other contributory factors and remedies.

With over three billion years of existence of the world, researchers have seen the need to turn to nature to solve most of the problems faced in not only construction industry but in other industries. The principles of biomimicry are natural laws that has helped nature maintain its self-regenerating status over this long period of time of the world’s existence. This study investigates the areas of construction projects to which biomimicry principles can be applied with a view to enhance the delivery of sustainable projects.

The study adopted the use of quantitative approach, and well-structured questionnaires were administered to professionals in the construction industry who are responsible for the design, construction and maintenance of buildings. A total of 243 answered questionnaires were analysed for this study. The variables were analysed using both descriptive analysis and further grouped into components by using factor analysis.

Data analysis for this study revealed that the principles of biomimicry can be applied to all the stages of building projects development and operations; this implies that the principles of biomimicry can be adopted at both pre-construction (design) and construction phases of developmental projects.

This study was limited to Nigeria, but the findings can be generalized for construction industry across the globe.

The study identified design stage of work, tiling and painting as the foremost aspects of construction projects where biomimicry principles are applicable. Furthermore, biomimicry principles are applicable to four major areas of construction, namely, early construction stage, finishing and services stage, foundation and frame stage and project planning stage.

A recurring problem for research into services is the question of validity – i.e. knowing which quality factors really are relevant for measurement and analysis. Retrospective data collection of customer perceptions has shortcomings in “fuzzy” and dynamic service processes. This paper focuses on the customer experience as an active resource for developing service systems.

Using a video‐based methodology for collecting naturally occurring data and a “think‐aloud” methodology for collecting real‐time user perceptions, the study reveals concrete cues in the service environment that determine quality from a customer perspective. The study then presents an empirical case to test and develop this methodology.

The study involves able‐bodied and disabled passengers using public transport and identifies environmental and processual factors that are critical for the customer base.

The study demonstrates the potential for more advanced observational methods in exploring service phenomena. The methodology used here has a higher face validity than traditional retrospective methods.

Using the sort of naturally occurring data presented in the present study, marketers and environmental designers could have a tool for obtaining more detailed, authentic and dynamic information on the actual purchase and consumption of service processes.

The described video‐based methodology gives rise to new ideas on how to develop research into services. In particular, it provides a tool for getting close to the essence of the service phenomenon. Such advanced observational methods are especially promising for investigating the contextual and processual aspects of service provision.

The purpose of this study is to investigate the effect of presence of buried flexible pipe on the bearing capacity of shallow footing. First, a model study is performed where shallow footing model is tested for its load settlement behavior, with and without the existence of buried PVC pipe lying vertically below the base of the footing.

The experimental set-up consisted of a steel box filled with sand at two different relative density values [RD = 50 per cent (medium dense) and RD = 80 per cent (dense sand)] and vertical load was applied on the model footing through hydraulic jack and reaction frame arrangement connected with a proving ring. Test results are verified numerically using commercially available finite element code PLAXIS 2D. With due verification, a parametric study has been conducted, numerically, by varying the range of input parameters, such as unit weight, angle of internal friction, diameter of buried conduit and the Elastic modulus of the soil to assess the pre cent reduction in the capacity of the foundation soil because of the presence of underlying buried flexible pipe.

Results show that for each footing, there exists a critical depth below which the presence of the buried conduit has negligible influence on the footing performance. When the conduit is located above the critical depth, the bearing capacity of the footing varies with various factors, such as geotechnical parameters of soil and location and diameter of the buried conduit.

It is an original paper performed to assess the presence of buried flexible pipe on the bearing capacity of the shallow footing.

The estimation of bearing capacity for shallow foundations in swelling soil is an important and complex context. The complexity is due to the unsaturated swelling soil related to the drying and humidification environment. Hence, a serious study is needed to evaluate the effect of swelling potential soil on the foundation bearing capacity. The purpose of this paper is to analyze the bearing capacity of a rough square foundation founded on a homogeneous swelling soil mass, subjected to vertical loads.

A proposed numerical model based on the simulation of the swelling pressure in the initial state, followed by an elastoplastic behavior model may be used to calculate the foundation bearing capacity. The analyses were carried out using the finite-difference software (FLAC 3 D) with an elastic perfectly plastic Mohr–Coulomb constitutive model. Moreover, the numerical results obtained are compared with the analytical solutions proposed in the literature.

The numerical results were in good agreement with the analytical solutions proposed in the literature. Also, reasonable capacity and performance of the proposed numerical model.

The proposed numerical model is capable to predict the bearing capacity of the homogeneous swelling soil mass loaded by a shallow foundation. Also, it will be of great use for geotechnical engineers and researchers in the field.

The purpose of this paper is to evaluate the co-seismic and post-seismic behaviors of an existed soil-foundation system in an actual alternately layered sand/silt ground including pore water pressure, acceleration response, and displacement et al. during and after earthquake.

The evaluation is performed by finite element method and the simulation is performed using an effective stress-based 2D/3D soil-water coupling program DBLEAVES. The calculation is carried out through static-dynamic-static three steps. The soil behavior is described by a new rotational kinematic hardening elasto-plastic cyclic mobility constitutive model, while the footing and foundation are modeled as elastic rigid elements.

The shallow (short-pile type) foundation has a better capacity of resisting ground liquefaction but large differential settlement occurred. Moreover, most part of the differential settlement occurred during earthquake motion. Attention should be paid not only to the liquefaction behavior of the ground during the earthquake motion, but also the long-term settlement after earthquake should be given serious consideration.

The co-seismic and post-seismic behavior of a complex ground which contains sand and silt layers, especially long-term settlement over a period of several weeks or even years after the earthquake, has been clarified sufficiently. In some critical condition, even if the seismic resistance is satisfied with the design code for building, detailed calculation may reveal the risk of under estimation of differential settlement that may give rise to serious problems.
