摘要

针对深埋硬岩隧洞即时性应变-结构面滑移型岩爆预测预警问题。以埋深 2 375 m 的某深部地下实验室 7#、 8#实验室发生的一次极强岩爆作为现场测试对象，基于钻孔摄像技术实现隧洞围岩内结构面展布可视化，通过岩爆诱发洞段与安全通过洞段围岩内结构面展布差异的对比分析、围岩弹性应变能分布特征分析与岩爆统计规律分析，对岩爆孕育中结构面的控制作用进行了深入的探讨。研究结果表明，深埋硬岩隧洞边墙与围岩内发育的结构面平行或是小角度(小于 30°)相交时具有更高的即时性应变-结构面滑移型岩爆风险。7#、8#实验室钻孔摄像结果显示，岩爆诱发洞段围岩内结构面近乎平行于边墙发育，3 处安全通过洞段围岩内结构面与隧洞边墙均为大角度 (大于 30°)相交。围岩内不同的结构面展布形态为岩爆孕育提供了不同的能量累积环境，当围岩内结构面平行于边墙或是小角度相交于边墙时，结构面的存在将有利于岩爆孕育。所有发生于锦屏二级水电站排水洞 SK8+200~8+800 洞段的岩爆统计数据表明，隧洞边墙与围岩内结构面相交夹角较小(小于 30°)的区域具有更高的即时性应变-结构面滑移型岩爆风险，这与 7#、8#实验室现场测试及数值模拟结果相吻合。

Abstract

For the immediate strain-structure slip rockburst prediction and warning in deep-buried hard rock tunnels， a super strong rockburst that occurred in 7-8# Laboratory of a deep underground labora- tory with a depth of 2 375 m was studied. Visualization of structural plane distribution in the surround- ing rock of the tunnel is realized using borehole camera technology. Through the comparative analysis of the structural plane distribution in the surrounding rock between the rockburst-induced tunnel sec- tion and the safe passage tunnel section， the analysis of elastic strain distribution characteristics of the surrounding rock and statistical law of the rockburst， the control function of structural plane in rock- burst breeding is discussed. The results show that the risk of rockburst increases when the tunnel side wall is parallel or intersects at a small angle (less than 30 degrees) with the structural plane developed in the surrounding rock. Borehole photography of the rockburst section in the 7#、8# Laboratory shows that the structural plane in the surrounding rocks of the rockburst tunnel section was almost par- allel to the side wall. In contrast， the structural planes in the surrounding rocks of the three safe pas- sage sections intersected with the side walls of the tunnel at large angles (greater than 30 degrees). Different structural plane distributions in the surrounding rocks provide different energy accumulation environments for rockburst breeding. The presence of structural planes parallel or intersecting with the side walls at small angles is conducive to rockburst breeding. The statistical analyses of all rockburst incidents in the section SK8+200~8+800 of the drainage tunnel of Jinping II Hydropower Station show that the area where the intersection angle between the tunnel side wall and structural plane in the surrounding rock was small (less than 30 degrees) had a higher risk of immediate strain-structure slip rockburst， which is consistent with the results of the 7#、8# Laboratory field tests and numerical simu- lations.
