摘要
为研究软土基坑开挖与邻近隧道的相互影响关系,以深圳地铁11号线前海湾站深基坑工程为背景,考虑坑周土体的蠕变和渗流耦合作用,分析软土基坑开挖变形规律及其对邻近5号线地铁区间隧道变形的影响,在此基础上,研究水泥搅拌桩锁淤加固技术对基坑及既有隧道变形的控制作用。
In order to study the,mutual influence between excavation of soft soil foundation excavation and adjacent tunnels,this paper takes the deep foundation excavation of Qianhaiwan .Station of Shenzhen Subway line 11 as the background and considers the creep and seepage coupling of soil around the foundation excavation.The silt reinforcement technology of cement mixing piles in the deformation control of foundation excavation and existing tunnels is studied by analyzing the deformation laws of foundation excavation and adjacent tunnels of subway line 5.
