摘要
采用隧洞松动圈理论,分析了围岩的松动变形机理,借此阐述了最佳支护时机的理念,对软岩隧洞的支护优化作出理论分析,并依据工程实例进行了说明,对隧洞工程施工具有重要意义。
The topic base on theory of broken-rock loop, analyses the distortion mechanics of surround-rock, expounds the concept of the optimum time point of support, then give a theory analysis about optimization design of soft-rock tunnel support, and has the indication by referring to the engineering example, so it is significant for the tunnel projects.
