以杭州紫荆港基坑支护工程为例，结合该工程的地层岩性及水文地质概况，采用Midas／GTS数值模拟软件，对预应力鱼腹梁支护结构总的位移、轴力、弯矩计算结果进行了分析，得到了支撑体系在基坑开挖过程中各个杆件的强度及基坑变形情况。%Taking the Hangzhou Zijing port foundation pit support engineering for example,combining with the engineering formation lithology and hydrology geology general situation,using Midas/GTS numerical simulation software,analyzed the total displacement,axial force,bending moment calculation results of pre-stressed fish-bellied beam steel support structure,gained the strength and foundation pit deformation situation of each bar of support system in foundation pit excavation process.
