摘要
结合某隧道的工程地质特点,采用ABAQUS对隧道开挖过程进行了数值模拟,分析表明:采用双侧壁导坑法,由于开挖步之间的相互影响,围岩的应力和变形都比较大,因此支护应紧跟,得出了数值模拟成果与现场监测结果规律基本一致的结论。
Combined with engineering geological characteristics of one tunnel numerical simulation of the excavation process of this tunnel is made using finite element software-ABAOUS. Analysis show support should be immediate flowing with tunneling because interactions in exca- vation process, which cause large stress and deformation of surrounding rock in twin side heading method. In the end conclusion obtained that simulation results are in good agreement with the on-site monitoring data.
