摘要
基于岩体的实际特点，将半解析法发展用于岩洞三维地震反应分析，通过数值计算取得了有多种形式断裂构造带的岩层中的洞室以及矿柱在地震与地表脉冲荷载作用下应力与运动的特征。
The semi─analytical method has been applied to thedimensional earthquakeresponse analysis of rock cavities based on practical feature ofrock body Numerical resultshave been abtained relating to stress and motion of cavities and mine columns in rock forma-tion under the seismic action or pulse load.
