深埋隧道岩爆预测与声发射特征
Prediction of rock-burst and analysis of acoustic emission characteristics in deep tunnel
摘要
Abstract
Rock-burst is a common type of dynamic destabilization geological phenomenon during underground projects excavation in high geo-stress areas.Taking Zhongnanshan highway tunnel in Qingling mountain as an example, through comprehensive investigation and theoretical analysis of rock-burst during 2# shaft excavation, combining with acoustic emission (AE) prediction techniques, we forecast and analyze the rock-burst, and obtained the acoustic emission (AE) characteristics and dynamic propagation regularities when the rock-burst is happening.Based on these, the comprehensive rock-burst controlling measures are proposed to ensure the safe construction.关键词
