牛岭水电站坝区工程地质条件评价

Evaluation of engineering geological conditions in the dam area of Niuling Power Station

文章分析了皖南牛岭水电站坝区的工程地质条件。将坝区岩体按结构、物理力学性质分为：整块结构体、层状结构体、碎裂结构体、散体结构体。对坝区断裂构造展布特点及其力学性质，特别是构造岩的工程地质特征进行详细评述。在此基础上，结合工程布局，对存在的工程地质问题进行分析与评价。

Engineering geological conditions in the dam area of Niuling Power Station are analyzed in this paper. According to rock structures and their physical and mechanical properties,rock masses in the dam area are divided into integrate structure,stratified structure,cataclastic structure and loosen structure. Distribution characteristic and mechanical properties of faults,especially engineering geological features of the fault rocks in the area are discussed in detail.And with construction arrangement considered, the existing engineering geological problems are evaluated.
