摘要
根据上海软土地区的20个案例,分析总结了隧道变形的一般规律。重点分析了影响隧道隆起和沉降的影响因素,并得出各影响因素与隧道竖向位移的关系;在此基础上对隧道隆起和沉降最大值进行了预测。预测结果显示隧道隆起和沉降与基坑开挖深度、隧道顶覆土厚度、基坑开挖面积等参数密切相关,实测值基本符合线性函数。
Based on the total 20 cases,this paper summarizes the basic rule of shield tunnels deformation. The main concern analyzes the influence factors of tunnels heave and settlement,and conclude the relationship between influence factors and the vertical displacement of tunnels. At last,it predicts the maximum heave and settlement of shield tunnels. The results reveals that tunnels heave and settlement have close relationship between excavation depth,tunnels buried depth,excavation area etc. The measured value is accord with linear function.
