Abstract: Liquefied silty soil can experience repeated liquefaction as a result of aftershocks or other subsequent earthquake events, which can be considered to be previous cyclic loading. The effect of previous cyclic loading on ...

Abstract: Large deformation of the surrounding rock may also occur in hard rock tunnels under certain circumstances. Taking the construction of the jointed and altered granite stratum in the Zangga Tunnel, China, as a case study, ...

Abstract: Soil clogging occurred in the early construction stage of Nanchang Metro Line 1, China, when an earth balance pressure (EPB) shield passed through the argillaceous siltstone with a total content of clay minerals of 40.5%. ...

Abstract: Deep excavation clearly impacts existing underlying subway tunnels and threatens their operational safety. The prediction of existing tunnel deformation induced by nearby excavation is a major concern for urban construction. ...

Abstract: An interesting operation has been developed to estimate the critical normalized surface settlement for shallow tunnels in undrained clay (idealized as a homogeneously Tresca material). The upper-bound finite-element method ...

Abstract: Because of the extreme terrain limitations and heavy traffic in congested urban areas, the supporting structures for deep excavations often undergo an asymmetric loading condition at two sides. This article reports the ...
