摘要
根据昆明—石林高速公路阳宗隧道S5型支护衬砌优化调整方案和XK38+ 92 6断面现场监控量测数据 ,进行位移反分析 ,得到计算所需的围岩弹性模量E和侧压力系数K0 ;然后运用有限元方法 ,对其试验洞段上下台阶开挖动态施工过程进行仿真数值模拟研究 。
On the basis of optimized design of S5 supporting lining and in situ monitoring data at XK38+926 section in Yangzong expressway tunnel, the E and Ko of the surrounding rock have been obtained by back analysis. The dynamic emulation of construction process has been conducted with FEM, the feedback control design is realized to control the construction.
