| 摘 要： | 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1～7cm.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。

| Abstract: | After excavation of the dam foundation of Fenhe Reservoir 2,a dislocation of rock mass along bedding fracture plane is found.The dislocation, with displacements of 1 cm to 7 cm,spread on almost the whole dam poundation which is composed of hard dolomite of Cambrian system.In this paper,the dislocation of rock mass at the dam foundation is analyzed and studied. The dislocation is a result ofground stress release after the excavation of the dam foundation. |
