鸭寨水库坝址左岸边坡为土质边坡,覆盖层成因复杂,物质组成不均,透水性及水理性差异较大.边坡开挖过程中出现开裂变形,通过分析边坡变形破坏迹象、位移监测特征及地质结构、水文地质条件等,采用三维地质建模、土层精细编录等工作,查明边坡变形破坏模式,分析边坡变形成因机制,为设计永久支护措施提供依据.
Deformation Analysis of the Left Bank Slope of the Yazhai Reservoir Dam Site
The left bank slope of the Yazhai Reservoir dam site is a soil slope.The overburden has a complex genesis,with heterogeneous material composition,and significant variations in permeability and hydrological properties.Cracking and deformation occurred during the slope excavation.By analyzing the signs of slope deformation and failure,displacement monitoring characteristics,geological structure,and hydrogeological conditions,three-dimensional geological modeling and detailed soil layer logging are employed to determine the deformation and failure mode of the slope.This analysis of the deformation causes and mechanisms provides a basis for the design of permanent support measures.
