摘　　要：以紫坪铺工程引水隧洞群为研究对象 ,完成了跟踪隧洞施工过程的围岩变形监控量测 ,获取了围岩动态稳定性态 ,并利用监测结果进行了仿真反演分析 ,得到了相应洞段的宏观力学参数与初始地应力场 ,为指导下半洞施工。For headrace tunnels at Zipingpu project , surrounding rock deformation monitoring was carried out during tunneling to get surrounding rock dynamic stability and artificial inverse analysis was carried out with monitoring results to obtain macro mechanics parameters and initial in situ stress field . These results provide reliable scientific basis for optimization design of tunnel construction and support in lower section.
