摘要

岩爆作为一种在深部地下工程中频发的地质灾害现象,已成为深埋隧道建设过程中的突出问题。以高楼山隧道为研究背景,利用自主研发的深部岩爆过程模拟试验系统,开展不同应力路径下应变岩爆试验,以模拟滞后型岩爆和瞬时型岩爆。试验过程中,对应变岩爆试验全过程红外热成像特征和声发射特征进行分析。结果表明:岩爆试件在开始加载至发生岩爆破坏的过程中,经历了平静期、裂纹扩展期、颗粒弹射期和岩爆发生期;试件在发生岩爆时,破坏发生区域温度迅速增长,最高温度往往伴随着颗粒弹射;试件在整个加载过程到最后破坏的过程中都伴随着能量的产生;滞后型岩爆试件和瞬时型岩爆试件声发射幅值和峰频变化规律大致相同,声发射累计能量也达到了相对较大的值。

Abstract

Rock burst is a geological hazard that frequently occurs in deep underground engineering and has become a significant problem during the construction of deeply buried tunnels. Using the Gaoloushan Tunnel as the research background, we utilized a self-developed experimental system for simulating deep rock burst processes to conduct strain rock burst experiments. These experiments were conducted under varying stress paths to replicate both hysteresis and instantaneous rock burst phenomena. The experiment involved analyzing the infrared thermal imaging and acoustic emission characteristics of the entire strain rock burst process. The results indicate that: The rock burst sample experiences a quiet period, crack propagation period, particle ejection period, and rock burst occurrence period from the initial loading to the point of rock burst failure under various stress paths. The temperature in the area of failure rapidly increases during rock burst, and particle ejection often accompanies the highest temperature. In addition, energy is generated throughout the loading process until the sample ultimately fails. The amplitude and peak frequency of acoustic emission are comparable between delayed and instantaneous rockburst samples, and the cumulative energy of acoustic emission is relatively high.
