摘要
本文利用ANSYS软件对小净距隧道在不同开挖方法下的围岩的变形及应力进行数值模拟。通过对先开挖隧道位移变化特征、围岩应力进行研究,得出Ⅲ级围岩条件下小净距隧道的合理开挖方法。
In this paper we will firstly numerical simulate the surrounding rocks and middle rock wall stress and displacement in different excavated method about neighborhood tunnel by ANSYS software. And then we will give the reasonable construction method about neighborhood tunnel in the Ⅲ grade surrounding rocks situation according to the study of variation characteristics about the stress and displacement in surrounding rock and middle rock mechanics characteristics in before - excavated tunnel
