Effect of Wall Deformation on Dewatering-Induced Ground Surface Settlement
Journal of Shanghai Jiaotong University (Science), 2020In practice, dewatering for pressure relief is commonly undertaken during ongoing excavation to secure bottom stability against basal upheaval. Simultaneously, through unloading, wall deflection is obviously observed. Noticing that both cause soil deformations, this research is to study the effect of wall deformation on dewatering-induced settlement. A

Shape of ground surface settlement profiles caused by excavation
Canadian Geotechnical Journal, 1998There are two general types of settlement profiles induced by excavation, the spandrel type and the concave type. Based on a regression analysis of the field observations of settlement curves with predominantly cohesive subsurface conditions, an empirical method for predicting the spandrel and concave settlement profiles is proposed.

Characteristics of wall deflections and ground surface settlements in Shanghai
Canadian Geotechnical Journal, 2005The characteristics of wall deflections and surface ground settlements at six deep multi-strutted excavations in Shanghai soft soils were studied and compared with those of similar case histories reported worldwide, particularly in Taipei and Singapore.

Effects of surface buildings on twin tunnelling-induced ground settlements
Tunnelling and Underground Space Technology, 2012Abstract The reciprocal effects of tunnelling-induced ground settlement and surface buildings are among the main concerns in urban underground projects. Interactions between buildings and tunnels can have major effects on the settlement trough. Therefore the factors involved in this interaction need to be assessed prior to construction.

TM-Informer-Based Prediction for Railway Ground Surface Settlement
Journal of Circuits, Systems and ComputersWith the acceleration of urbanization, subway construction has become a key part of urban development. However, shield construction often needs to cross existing railway lines, which requires accurate prediction of ground surface settlement of railway operation facilities to ensure railway safety and smooth construction.

Analysis of buried pipelines subjected to ground surface settlement and heave
Canadian Geotechnical Journal, 2015This paper presents an analytical methodology for the calculation of internal forces and strains developing in continuous buried pipelines that cross geotechnically problematic areas and are susceptible to permanent ground surface settlement or heave. Material nonlinearity effects are introduced in the solution via an iterative procedure, while taking

Tunnelling and Underground Space Technology, 2006
The construction of underground tunnel plays a more and more important role on the development of big cities. One of the most important problems caused by the construction of tunnel is that underground excavation will cause large settlements of ground buildings. And it heavily affects the safety of the building.

Analysis of ground surface settlement due to shallow shield tunnels
International Journal for Numerical and Analytical Methods in Geomechanics, 1977When shallow tunnels are constructed under streets and buildings, surface settlement due to the tunnelling and its control becomes essential to prevent any environmental problems. This paper deals with finite element analysis and a simplified numerical method for computing the surface settlement due to tunnelling. The computed results are compared with

Evaluation of wall deflections and ground surface settlements in deep excavations
Arabian Journal of Geosciences, 2014A study to illustrate the ground surface and wall movements due to excavation is undertaken based on two-dimensional nonlinear finite element (FE) modeling and analysis. The FE model and nonlinear solution strategy are built in the open-source software platform, OpenSees, of the Pacific Earthquake Engineering Research Center.

Ground Surface Settlements due to Underground Works
2007Ground surface deformations due to tunneling are crucial in urban regions where damages to surface structures and utilities should be prevented. In this paper the detection and monitoring of the vertical displacements of an area situated above the axis of one of the Athens METRO tunnels, where damages on constructions were observed during the ...
