摘　　要：将牙根水电站松动岩体按节理分布发育规律分为三个区,基于各区结构面组合关系,分析了松动岩体各区结构面的成因机制及模式,构建了其变形演化的地质模型,并判断了各区的变形破坏模式,有助于认识其空间发育规律、工程地质特征及发展趋势,对评价工程稳定性有重要指导意义。According to the development characteristics of joint distribution, the dynamo relaxed rockmass of Yagen Hydropower Station can he divided into three areas. Based on the composition relationship of the structural plane in different areas, the cause mechanism of the structural planes in different areas of dynamo relaxed rockmass is analyzed. And the evolution deformation of the geological model is established. Then the various failure modes of deformation are pointed out. Thus, it is useful for us to understand the law of development, engineering geological characteristics and developmental trend of the dynamo relaxed rockmass, which plays an important role in evaluating engineering stability.
