公路隧道开挖的ANSYS三维仿真分析

Simulation analysis of ANSYS three dimensional for excavation of highway tunnel

结合具体工程,对公路隧道的设计与开挖过程进行ANSYS三维仿真分析,获得隧道围岩地层的应力、位移的分布规律,进而验证隧道设计参数的合理性,同时判断所选用的施工方法能否保证隧道围岩的稳定。

Combined with practical work, a simulation analysis of ANSYS three dimensional for design and excavation of road tunnel was used. The numerical simulation reveals the distribution characteristics of displacement and stress of the wall-rock. The rationality of tunnel design parameters was validated. At the same time the stability of wall-rock of road tunnel in the condition of the chosen construction method was judged.
