| 摘 要： | 根据麻栗场隧道现场监测结果,采用弹塑性位移反分析的方法,得到反映围岩综合性状的弹性模量E、地应力侧压力系数K的值.通过与临近断面的监测结果进行对比,检验反演参数的合理性.结果表明,反演所得参数基本反映了工程区岩体的实际物理力学性状,对隧道施工和设计具有一定的指导意义. |

| Abstract: | According to field monitoring results of the MaLichang tunnel,using the elastic-plastic displacement back analysis method,the value of rock modulus E and lateral pressure coefficient K can be obtained,which can be used to reflect the synthetical characters of rock.Compared with the monitoring results of the adjacent section,the rationality of inversion parameters could be verified.Finally,the inversion parameters basically reflect the physical and mechanical properties of the project area.This kind of analy... |
