Ground surface settlements of sands densified with explosives
Proceedings of the Institution of Civil Engineers - Ground Improvement, 2016Blast densification has long been used to densify loose, saturated sand deposits. Although it is an economically feasible approach to densify large areas, it is not widely used in engineering practice as the design is mostly empirical and some verification tests, such as the cone penetration test, standard penetration test and shear wave velocity test,

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

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.

A theoretical study on ground surface settlement induced by a braced deep excavation
European Journal of Environmental and Civil Engineering, 2020Ground surface settlement (GSS) is one of the major concerns in design and construction of a deep excavation. This paper proposes an analytical approach for the prediction of GSS induced by a braced deep excavation.

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.

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

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.

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.
