With the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. During excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...

Ground movements during tunnel excavation are varied in magnitude and trend depending on several factors including the tunnel geometry, ground conditions, excavation methods, and support measures, etc. There exist several empirical and semi-empirical formulas available for predicting ground movements. These conventional methods, however, do not simultaneously take into consideration all the fac...

Currently, new housing in city centers is more and often developed on small plots of land, or existing buildings such are rebuilt to an extent that only their façade walls remain. In both cases, as a rule, deep excavation also made, either at the object within its area. Serious damage occurs because carried out work. It not possible accurately determine response building deformation associated ...

A three-dimensional finite element model has been developed at Oxford University to study the effects of subsidence from soft ground tunnelling on adjacent surface structures. Simulation of excavation and the ground loss associated with tunnelling are incorporated in the model. Surface buildings are also included, as groups of interconnected two-dimensional façades composed of an elastic no ten...

the construction of underground tunnel plays a more and more important role in the development of big cities. one of the most important problems caused by the construction of the tunnel is that underground excavation will cause large settlement of the ground and buildings. previous studied showed the difference between numerical and experimental results. in this study the case study of niyayesh...

A data-driven indirect approach for predicting the response of existing structures induced by excavation is hereby proposed based on making full use monitoring data during excavation, which can predict deformation history research object excavation. In this article, a machine-learning-based model framework implementing constructed and treatment key issues in design implementation method describ...

In this study, the effect of deep excavation on the seismic response of RC moment resisting building systems has been studied. Deep excavation can cause significant changes in the stress and strain levels of soil environment and also changes in the propagation of seismic waves. This leads to permanent displacements in the foundation system. In this study, three RC building systems, i.e. 5, 10, ...

In order to ensure the safety and stability of existing old masonry structure houses in process dewatering excavation super deep foundation pit subway, support form a water stop curtain combined with bored cast-in-place piles internal is adopted, rotary jet grouting are constructed around houses, sleeve valve pipes embedded, soil house grouted strengthened. The deformation building analyzed by ...
