摘　　要：通过详实的野外地质调查,从岩体结构条件及岩性组合研究入手,对岷江上游一个水电站枢纽区边坡结构特征和典型失稳破坏模式作了精细阐述。从影响边坡稳定性的主要因素和加固处理目的出发,对工程区边坡岩体结构和地质结构类型分别进行4大类9亚类与6大类11亚类的详细划分。在此基础上,提出和建立了4大类9亚类工程区边坡主要变形破坏的模式机理,从而为施工期的边坡安全反馈分析及边坡加固防治对策的采取和支护设计优化提供了重要的理论依据。Based on detailed geological investigation and research, engineering geology factors, this paper discusses the engineering slope types, rock mass characteristics and kinds of typical destabilization patterns in a hydropower station on the upriver of Minjiang River systematically. Based on the leading factors affecting slope stability and beginning with the aim in the process of stabilization, 6 groups and 11 sub-groups and 4 groups and 9 sub-groups are specifically divided in allusion to engineering slope types of geological structure and rock mass structure, respectively. According to the study mentioned above, the mechanism of deformation-failure pattern of the slopes in the engineering region is concluded and 4 groups and 9 sub-groups are established. It is an important theoretical basis for feedback analysis, formation mechanism, optimum design of excavation slope in the engineering region. This is closely related to the safety of stabilization.
