自动伺服系统中斜支撑的运用与实践

Application and practice of inclined support in automatic servo system

通过在地铁车站内运用自动伺服系统斜支撑的方法,可严格控制基坑变形,通过有限元分析,对轨道交通9号线芳甸路站项目的钢支撑自动伺服系统建立模型,得出围护结构侧移值和坑外地表沉降值,该工程解决了目前普遍基坑中无法运用斜支撑的施工难点。

The inclined support in automatic servo system can control the deformations during the construction of excavation. By finite element analysis,this paper get the lateral displacement value of the excavation support structure and the settlement value of the ground outside the excavation through setting up the model of fangdian road station of shanghai rail traffic No. 9 line. This project solves the difficulty of using inclined support in foundatoin pit.
