盾构隧道混凝土管片受力分析

Analysis on concrete segment stress in shielding tunnel

以杭州地铁一号线下沙开发区某区间隧道工程成环管片为研究对象,利用ANSYS软件建立成环管片数值模型,分析了管片在土中的受力情况,同时结合在本工程实际施工中管片出现的一些情况,得到较可靠的结论。

Taking Hangzhou subway line No.1 interaction tunnel engineering circular segment in Xiasha development region as the research target,the paper establishes the circular segment numerical model by using ANSYS software,analyzes the stress conditions of segments in the earth,and obtains rather reliable conclusions by integrating with some actual segment conditions occurring in the engineering construction.
