摘要
利用M IDAS/GTS有限元软件进行隧道开挖过程的模拟,通过改变隧道间的净距值,分析了隧道围岩的位移、主应力分布与净距之间的关系,得出了适用于本文研究的小净距隧道工程的合理净距建议值。
Using the finite element software MIDAS/GTS, numerical simulation on the tunnel excavation process were carried out and the relationship between the tunnel interval and displacement of surrounding rock, principal stress distribution was analyzed by changing the value of the interval values. The reasonable interval suggested value that is the same with the small interval tunnel project concerned is obtained.
