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 ...

Abstract: This paper presents the performance of an excavation with cross walls based on field observations and numerical analysis results. A small strain constitutive model was used in the analysis. By comparing the movements of ...

Abstract: This study proposes a simplified reliability-based design (RBD) method for the serviceability limit state (SLS) of excavations considering cross walls. Although the effects of cross walls are highlighted, the proposed ...

Abstract: This paper presents the performance of an excavation using the top-down construction method. Strut loads, wall displacement, wall bending moment, ground surface settlement, pore-water pressure and bottom heave were measured. ...

Abstract: Excessive lateral diaphragm wall displacement and the associated ground settlement are often the primary cause of damage of nearby buildings. It is therefore imperative to minimize diaphragm wall displacement during basement ...

Abstract: A nonlinear, three-dimensional finite element technique for deep excavation analysis is proposed in this paper. The technique as well as the analytical procedures for modeling the excavation processes were coded into a ...

Abstract: To minimize the ground settlement induced by the excavation, the column type of ground improvement has been used in many parts of the world, possibly due to the fact that this type of soil improvement is relatively easily ...

Abstract: This paper presents a framework for a fully probabilistic analysis of the potential for damage to buildings adjacent to an excavation. Herein, the damage potential index (DPI), which is a function of angular distortion and ...

Abstract: Spatial variability of soil undrained shear strength is usually not rigorously considered in the design of basal heave for deep excavations. In this study, the slip circle method is employed to investigate how the required ...
