| 摘 要： | 通过论证比较，按照隧道围岩主要工程地质特征，围岩岩体结构及结构面特征，水文地质特征，围岩弹性纵波波速，变形系数，泊松比，内摩擦角，软化系数等指标，重新划分和确定了围岩类别，分析了产生围岩类别偏差的原因，以期对同类工程勘察起到借鉴和参考作用。

| Abstract: | The new classification for the surrounding rock has been made by demonstrating and comparing, according to the indices of characteristics of engineering geology, rock mass structure and structure plane, hydrogeology,velocity of longitudinal wave,coefficient of deformation,Poissons ratio,internal frictional angle and coefficient of softness. Then reasons for the deviation in classifying surrounding rock has been analyzed and the reference effect on the similar engineering investigation has been ensured. |
