| 摘 要： | 围岩参数位移反分析中常常因为时空效应导致计算失真，采用相对位移反分析法可以有效地解决时空效应引起的岩石蠕变对反分析结果的影响。通过实际工程隧洞开挖施工过程中的洞壁位移监测结果，利用相对位移反分析法研究围岩参数，为设计提供参考。

| Abstract: | Time-space effect often brings about distortion of calculation in back analysis of surrounding rock displacement and adoption of the back analysis method of relative displacement can effectively solve the influence problem of rock creep caused by time-space effect on back analysis results.The study of surrounding rock parameters using the back analysis method of relative displacement based on the tunnel wall displacement monitoring results obtained in excavation of tunnels of practical construction projects gives a reference to design of tunnels. |
