摘要
在通过工程地质调绘、收集周边地质资料、物探等传统勘测手段对硐室围岩综合分析的的基础上,采用ABAQUS数值模拟的手段,分析计算洞室现状的稳定性、洞室扩建围岩应力的变化及洞室开挖对周边环境的影响。
Based on the comprehensive analysis of the surrounding rock by engineering geological mapping,collection of surrounding geological data,geophysical exploration and other traditional survey methods,the stability of the cavern status,the change of surrounding rock stress of the cavern expansion and the impact of the cavern excavation on the surrounding environment are analyzed and calculated by using ABAQUS numerical simulation.
