由寒武系坚硬白云岩组成的汾河二库坝基开挖后，岩体沿顺层开裂面发生错位，错位波及几乎整个坝基，错距达 １～７ ｃｍ 。本文对坝基岩体错位进行了分析研究，认为岩体错位是基坑开挖后地应力释放的结果
After the excavation of the Fenhe II reservoir foundation made up of the Cambrian hard dolomite, the rock mass is dislocated along the bedding plane of the bedding layer. The dislocation affects nearly the entire dam foundation with a stagger of 1 ~ 7 cm. In this paper, the dislocation of the dam foundation is analyzed, and the dislocation of the rock mass is the result of the release of the earth stress after excavation
