浅埋、偏压、软岩隧道开挖与锚杆加固的试验研究

EXPERIMENTAL STUDY ON THE EXCAVATION AND REINFORCEMENT OF SHALLOW-BURIED TUNNEL IN SOFT ROCKMASS AND UNDER UNEVEN PRESSURE

本文通过模型试验,研究了在均匀连续介质中浅埋偏压隧道的合理开挖方法、不同布锚方式对围岩稳定性的影响及加固效应.所获得的成果,对类似条件下的隧道设计与施工具有重要的指导意义。

This paper presents the result of an experimental study on the suitable me-thod of tunnelling in homogeneous soft rockmass, the influence of differentrockbolt arrangement on rockmass stability and the reinforcing effect of surficialrockbolts in excavation. The result has important guiding significance to thedesign and construction of tunnels under similar conditions.
