摘　　要：在岩土工程勘察中,对岩体的分类主要依据岩体完整程度来划分,通常用岩体与岩块的压缩波速度之比的平方来判断完整程度;用钻孔全孔壁光学成像法来辅助判断,可起到更加直观的描述。In the geotechnical investigation,the classification of rock mass is mainly based on the degree of integrity. The integrity is usually judged by the square of the ratio of the compression wave velocity of rock mass to rock block. It can be described more intuitively by using borehole full hole wall optical imaging method.
