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.
