Abstract: The buttress and cross walls are commonly used to control wall deformation induced by deep excavations. In this paper, the optimum performance of the buttress wall along two cross-wall intervals in deep excavations is ...

Abstract: This study aims to investigate the failure mechanism of structural support systems in braced excavations. The three-dimensional finite-element method (FEM) was used to model the complexity of real geometry by considering ...

Abstract: The ground-improvement technique is commonly used to restrain the wall displacement induced by excavation and resist the basal heave for deep excavations in soft clays. In this paper, a three-dimensional finite-element ...
