摘要
本文以某大厦项目深基坑工程为背景,在原有的锚索支护基础上,依据该工程地质条件特征,进行了验证性的基坑支护方案变更,运用ABAQUS有限元软件建立三维模型,同时考虑车辆荷载乘以冲击系数转化为静载时的影响,对围护墙的拉锚支撑方案局部变更后进行结构的受力变形分析,并与实测数据对比,分析结果均满足受力变形要求,验证了该类地质条件较好,可以适当地减少锚索的数量,具有可行性。
In this paper,taking the deep foundation pit engineering of a building project as the background,based on the original anchor cable support,according to the characteristics of the geological conditions of the project,a verification change of foundation pit support scheme is carried out.The ABAQUS finite element software is used to establish a three-dimensional model.At the same time,considering the impact when the vehicle load is multiplied by the impact coefficient and converted into static load,the stress deformation analysis of the structure is carried out after the local change of the retaining wall's anchor support scheme.Compared with the measured data,the analysis results meet the stress deformation requirements,which verifies that this kind of geological conditions are good,and it is feasible to reduce the number of anchor cables appropriately.
