Study on Typical Destabilization Models and Development Condition Of The Engineering Slopes In Zipingpu Water Conservancy Project of Minjiang

摘要

Based on detailed geological investigations and researches, engineering geology factors, engineering slope types, rock mass characteristic and kinds of typical destabilization patterns in Zipingpu water conservancy project of upriver Minjiang River have been systematically discussed in this paper. Leading factors which affect slope stability together with aim at the process of reinforcement treatment, 6 groups and 11 sub-groups are specifically divided in allusion to engineering slope types of geological structure, respectively. According to the study mentioned above, the developmental condition of definitive destabilizing failure models corresponds with slope types in the process of research. Therefore, the mechanism of deformation-failure pattern of the slopes in the engineering region has been concluded. It is the important theoretical gist for feedback analysis, formation mechanism, and optimum design of excavation slopes in engineering region, which is closed, related to safety of stabilization. It is also significant to reference typical destabilization and deformation/failure models to be provided for the similar deformation and failure model of engineering high slopes.
