摘要
通过对东山隧道现场量测得到水平收敛及拱顶下沉的数值分析,利用ANSYS有限元法程序模拟围岩初始应力场,初始应力场代替自重应力场数值模拟隧道开挖,通过计算,评价支护结构的稳定性,优化支护结构体系。
Through the Dongshan tunnel at the scene of a measurement to be the level of convergence and the dome subsidence data analysis, using ANSYS finite element method simulation of initial rock stress field, the initial stress field in place of self-weight stress field numerical simulation of tunnel excavation. By calculating, evaluating the stability of supporting structure, optimize the system supporting structure.
