【摘要】 利用南水北调中线西甘池试验洞变形量测数据,采用三维有限差分程序FLAC3D进行反分析计算,所得围岩地质力学参数和现场原位试验结果基本一致,使用的方法和所得结论可用于隧洞围岩稳定计算、优化设计和指导施工。更多还原

【Abstract】 Based on the measured deformation data of Xiganchi Trial Tunnel for the Mid-route of the South-to-North Water Transfer Project,a back analysis is made on with the 3D finite difference procedure FLAC3D;from which the obtained mechanical parameters of the surrounding rock is basically coincident with those from the in-situ test concerned,and then the methods and conclusions given herein can be used for the calculation on the stability of the surrounding rock of the tunnel,so as to optimize the design and guide the construction.更多还原
