层面裂隙属于构造裂隙。它的形状、分布、性质与区域应力场有关。在基岩地区的水文地质勘察中,应重视对层面裂隙的研究,原因是层面裂隙的数量多,规模大,展布广,并沟通其它裂隙。它对地下水的埋藏、分布、运移、汇集有着明显的影响。而且,随着岩层倾斜度的变化,它对地下水的运移、富集作用是不同的。一、缓层面裂隙对地下水的富集作用 Layer cracks belong to the structural fracture. Its shape, distribution, nature and regional stress field. In the hydrogeological survey of bedrock areas, attention should be paid to the study of the level fractures because the number of the level fractures is large, the scale is large, the exhibition is wide, and other fissures are communicated. It has a significant impact on the burial, distribution, migration and collection of groundwater. Moreover, with the change of rock slope, it has different effects on groundwater migration and enrichment. First, the slow-level surface fissures enrichment of groundwater
