隧道软弱围岩初支变形的常见原因及治理要点研究

Research on Common Causes and Key Points for Treatment of Initial Support Deformation of Weak Surrounding Rock in Tunnels

在隧道软弱围岩施工过程中,设置初期支护主要是为了确保隧道工程的安全性,并提升施工效率,减少安全事故的发生概率。在具体操作中,需要利用超前锚杆起到一定的预加固作用,以便保障掌子面的稳定性,同时有效控制隧道围岩松软变形问题,防止出现岩体失稳现象。论文主要对隧道软弱围岩初支变形的常见原因进行分析,并探究治理和预防措施,旨在进一步提升隧道软弱围岩初支施工质量,保障整体隧道工程的安全施工。

During the construction of weak surrounding rocks in tunnels,the main purpose of setting up initial support is to ensure the safety of tunnel engineering,improve construction efficiency,and reduce the probability of safety accidents.In specific operations,it is necessary to use advanced anchor rods to play a certain pre reinforcement role,in order to ensure the stability of the tunnel face,and effectively control the problem of soft deformation of the tunnel surrounding rock to prevent rock mass instability.The paper mainly analyzes the common causes of initial support deformation of weak surrounding rock in tunnels,and explores governance and preventive measures,aiming to further improve the quality of initial support construction of weak surrounding rock in tunnels and ensure the safe construction of the overall tunnel project.
