| 摘 要： | 在新奥法的隧道设计理念中,施工中的变形监测成为其重要的组成部分。为实时掌握青藏铁路关角隧道的围岩变形和支护结构的受力特点,通过采用JSS30A型数显收敛计对围岩进行周边位移量和拱顶下沉量的监测,研究其围岩动态变化,预测和确认其最终稳定时间。对隧道安全施工和二次衬砌的施工时间具有重要的指导意义。

| Abstract: | In the tunnel NATM design concept,Monitoring and Survey of Tunnel NATM becomes an important part,For controlling the real-time characteristics of surrounding rock deformation and supporting structure in the Qinghai-Tibet railway guan jiao tunnel,by adopting the JSS30A digital convergence meter,monitoring the peripheral displacement and dome subsidence of the rock,researching the rock mechanics condition,foreseeing and confirming the stabilize time.This is of important meaning to the safety construction. |
