摘要
结合某隧道监测断面各施工阶段位移变化情况,应用MIDAS GTS软件建立三维模型,通过反分析计算确定了弹性模量E及侧压力系数K0的取值范围。通过对隧道各施工阶段的变形情况进行模拟,采用黄金分割法对隧道拱顶下沉和净空位移量测值进行了反分析计算,与实测值对比分析后说明计算结果准确可靠。
Based on the displacement variation of a tunnel monitoring section at each construction stage,in this paper,the MIDAS GTS software was used to establish a 3 D model,and the value range of the lateral pressure coefficient K0 of the elastic modulus E was determined through reverse analysis and calculation.By simulating the deformation of the tunnel at each construction stage,the reverse analysis was carried out to calculate the tunnel vault settlement and clearance displacement measurement data using golden section method.The calculation result was proved to be accurate and reliable by comparing with actual measured value.
