高地应力隧道岩爆施工风险评估及管控措施

Risk Assessment and Control Measures for Rock Burst Construction in High Stress Tunnels

依托某隧道项目,通过收集项目的设计文件、地勘报告,分析项目的地应力背景、岩体的物理力学特性、对岩爆进行了预测与综合评价。并建立了高地应力隧道岩爆施工风险评估指标体系,提出了相应的控制措施。

Based on a certain tunnel project,the design documents and geological survey reports of the project were collected to analyze the geological stress background,physical and mechanical properties of the rock mass,and predict and comprehensively evaluate rock bursts.And a risk assessment index system for rock burst construction in high stress tunnels was established,and corresponding control measures were proposed.
