摘要

沈阳地铁十六标段过新开河段区间隧道采用明挖施工，基坑采用钻孔灌注桩联合钢支撑结构体系以维护基坑稳定。开挖过程中，对桩体位移、桩体内钢筋应力、钢支撑轴力以及地面沉降等进行监测。监测结果和实际工程效果表明，采用钻孔灌注桩联合钢支撑结构体系可以维护基坑稳定，减少基坑开挖对周围环境的影响。

Abstract

The open-cut technology is used in the Xinkai River running tunnel of the 16th bid of Shenyang subway engineering

and the cast-in-place pile system surported by steel brace is applied in foundation pit excavating.During the excavating

the pile displace- ment

the stress of the reinforcing steel bar

the axis stess of the steel brace and the ground subsidence are monitored.The results got by monitor and the effects of the engineering indicate that the foundation pit using cast-in-place pile system is safe

and the foundation pit excavation has little effect on the environment.
