摘要
结合中梁山隧道西段施工现场的实测数据,分析了该段围岩变形的条件和规律,并对各类围岩的各测线进行了量测数据回归分析,导出了各类围岩的稳定性判据,给出了最佳初期支护及二次衬砌时间。
In this paper the author' s study on the monitoring measurement technique of NATM,the regularity and conditions of the country rock deformation are analysed based on the site measurement data in the west section of Zhongliangshan tunnel. The regression analysis of measure data for different measure lines of vavious country rock is done by the use of self-compiled CRAP program. The stability criterion for various rockmass and optimum time for primary and permanent support are provided. The conclusion available could conduct the theoretical research of NATM deeply as well as tunnel design and construction.
