摘　　要：该文以军工路越江隧道浦西岸上段基坑工程为背景,研究分析了基坑开挖施工过程中围护墙体变形、钢支持轴力的监测结果,得出基坑开挖过程中支撑轴力、墙体水平位移的基本规律,为类似基坑工程设计、施工提供参考依据。Taking the Jungong Road Crossing-river Tunnel Puxi Bank Section Foundation Pit Project as the background,the article studies and analyzes the deformation of the enclosure wall body and the monitoring result of steel supporting axial force.The basic law of the supporting axial force and the wall horizontal displacement in the course of pit excavation are given,which can provide the reference and basis for the design and construction of the similar foundation pits.
