Evaluation of Supporting Structure Stability on New Fault of Xuefengshan Tunnel Zk97+830

Abstract:

For Xuefengshan tunnel, supporting stability in the course of tunneling is analysed by use of changed parameters of construction and design, which is based on construction simulation of left tunnel in the fault. It was shown that tunnel structure can keep stability after advanced little pipe injection grouting is used and supporting parameters and excavation model are changed. It can provide scientific evidence for directing construction and ameliorating supporting parameters, and it can reduce loss which is resulted by heavy collapse because of incorrect support.
