摘要
基于岩石在爆炸应力波和爆生气体作用下的损伤断裂机理,对隧道掘进爆破对围岩的损伤与危害作用、爆破地震效应和安全判据标准进行了理论和实验研究.通过对渝怀铁路圆梁山岩溶隧道、青藏铁路风火山高原冻土隧道等掘进爆破中的爆破地震波的监测和分析,确定了隧道掘进爆破的安全判据和技术标准.
Based on the rock damage and fracture mechanism in the effects of the explosive stress wave and the detonation gases,the damage mechanism on surrounding rock mass,the seismic effects and the safe criterion of explosion in tunnel blasting were analyzed with theoretical and experimental method.The safe seismic criterion and technique rules on excavation blasting were proposed by measureing the seismic waves in the excavation blasting of Yuanliangshan karst tunnel and Fenghuoshan frozen earth tunnel.
