摘要
四川南部某地下硐室在开挖过程中,形成较大面积的超挖,在现场调查、资料收集的基础上,利用不同方法对边墙、拱顶等不同部位的围岩岩体质量进行了划分,并根据划分结果,对危岩稳定性进行了综合评价。
An underground rock cavern in southern Sichuan was over-excavated during the construction.This paper presents the evaluation results of rock mass qualities at side walls and arches based on the site investigations and desk studies.The stability of the surrounding rock mass is also analyzed.
