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.

Key words: cast-in-place pile, pile displacement, surface settlement, steel brace
