| 摘 要： | 地质力学分类方法是目前工程地质围岩分类中综合多因素分类方法中较常见的一种。它主要是通过完整的岩石强度、岩石质量指标（RQD）、节理间距、节理状态和地下水条件这五个参数来对岩体进行量化打分，最终通过总得分来对围岩进行分类。本文就是通过该分类方法对澜沧老厂铅锌矿的巷道围岩进行质量评价。

| Abstract: | At present,geomechanical classification is a common method for the classification of wall rock in engineering geology.This method is based on five parameters such as strength of complete rock,quality index(RQD) of rock,joint space,joint state and groundwater conditions.This paper uses this method for assessing the quality of underground opening workings in the Laochang Pb-Zn deposit,Lancang. |
