摘要
近年来,城市地铁建设发展的越来越快,基坑的开挖深度越来越深,因此,基坑的施工安全备受关注,尤其是深基坑施工。深基坑工程的施工是一项复杂的系统工程,当周围环境相对复杂且要求比较严格时,单纯通过理论分析与预测就不是很准确,由此可以体现出基坑监测的重要性。其中钢支撑作为深基坑工程的水平支护结构,对深基坑施工安全起着至关重要的作用。文中结合沈阳地铁9号线换乘车站深基坑工程,该工程四周存在较多既有建筑物,工程环境相对比较复杂,深基坑的施工具有相当的挑战性。采用"理正深基坑6.01"深基坑结构设计软件主要对基坑内的钢支撑轴力计进行数值分析。主要通过改变钢支撑首末位置、改变钢支撑竖向及水平方向间距来分析对基坑周围桩体水平位移的影响。
In recent years,the development of urban metro construction is faster and faster,the depth of Foundation pit excavation is deeper and deeper,so,much attention has been paid to the foundation pit construction safety especially in deep foundation pit construction.Construction of deep Foundation pit project is a complicated systematic project,when the environment is relatively complex and stringent requirements,simply is not very accurate theoretical analysis and forecast,which can reflect the importance of Foundation pit monitoring.Steel supports is the horizontal supporting structure in deep Foundation pit engineering,it plays a crucial role for deep Foundation pit construction security.Based on the deep Foundation pit of Shenyang Metro Line 9 line transfer station project,there are a lot of buildings around this project,engineering environment is relatively complex,construction of deep Foundation pit is very challenging adopts "deep Foundation pit of lizheng 6.01" deep excavation structural design software for in numerical analysis of bracing axial force in Foundation pit.Mainly by changing the end positions of steel,change the steel support vertical and horizontal spacing to analysis on piles around the pit horizontal displacement effects.
