深部高应力硐室围岩稳定性分析

针对深部高应力条件下硐室围岩变形严重、围岩稳定性差的问题，采用现场调查、试验研究和数值模拟等方法，分析了硐室围岩变形破坏特征和围岩变形机理，对硐室围岩矿物成分进行了分析，模拟了相邻硐室和巷道开挖对硐室围岩的扰动影响，对硐室围岩进行了松动圈窥视探测，确定了硐室支护方案。结果表明，新的支护方案提高了硐室的安全稳定性，硐室支护效果良好。

Stability analysis of surrounding rock of deep high stress chamber

In view of the serious deformation and poor stability of the surrounding rock of the chamber under the condition of deep high stress，the deformation and failure characteristics and deformation mechanism of the surrounding rock of the chamber were analyzed by means of field investigation，experimental research and numerical simulation，the mineral composition of the surrounding rock of the chamber was analyzed，and the disturbance effect of adjacent roadway and chamber excavation on the surrounding rock of the chamber was simulated.The loose circle of the surrounding rock of the chamber is peeped and detected，and the chamber support scheme is determined.The results showed that the new support scheme improves the safety and stability of the chamber，and the chamber support effect was good.
