2) F7 fault
F7断层
1.
The Elastic-visco Displacement Back Analysis of Wushaoling Tunnel F7 fault;
乌鞘岭隧道F7断层的黏弹性位移反演分析
2.
This displacement of the rock wall is not convergence in a long time after excavating in F7 fault of the Wushaoling tunnel,and the time for lining executed can not meet the request of "The Code for Design of Railway Tunnel ".
乌鞘岭特长隧道11#斜井处正洞在穿越F7断层时,由于隧道埋深大,断层岩体破碎,岩体完整性差,围岩自稳能力弱,受挤压影响等,开挖后围岩变形长时间不收敛,50d后的变形仍有2—4mm/d,累计最大变形量已超过60cm,部分地段严重侵限,不能满足《铁路隧道设计规范》关于二次衬砌施做的规定。
3.
Combined with the measurement data from Wushaoling tunnel traversing the F7 fault,and taking the surround rock as isotropic body,the initial ground stress is postulated to be in well-proportioned distribution,the tri-element model was utilized.
结合乌鞘岭隧道穿越F7断层所取得的量测资料,将计算区域内的岩石视为均质各向同性体,初始地应力假设成均匀分布,采用三单元模型和工程实践及三维有限元分析结果,围岩变形规律通过引入位移释放系数考虑测点的时空效应,对有限元黏弹性问题进行优化反演分析,得出围岩区域内的水平侧压力系数和所使用模型中的弹性模量和黏滞系数,为挤压性断层中隧道的支护设计、施工组织提供可靠的依据。
3) F7 gene
