摘要
根据昆明—石林高速公路阳宗隧道S5型支护衬砌设计优化调整方案和XK38+926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K_0;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,从而反馈调整和指导施工。
On the basis of S5 optimized design drawing of Ⅲsurrounding rock masses and measured data in site in Yangzong expressway tunnel, obtaining E and K0 of surrounding rock masses by back analysis; the dynamic emulation simulatation of construction process has been conducted with FEM methods, feedback controlling design is realized and the construction is controlled.
