摘要
Abstract
The tension anchor cable support structure is commonly used in adjacent foundation pits.This article focuses on an asymmetric deep foundation pit project using tension anchor cables.A finite element HS small constitutive model is used for numerical simulation,and deformation analysis is carried out for different excavation sequences.The results indicate that the horizontal displacement depth curve of the support structure pile obtained through numerical simulation is close to the measured value.Adopting a shallow to deep excavation sequence is more advantageous for controlling the deformation of the support structure,providing reference for the design and construction of similar foundation pits.关键词
