Analysis and Research on Seepage Characteristics of Concrete Face Rockfill Dam
In this paper,the seepage analysis theory and finite element method are used to calculate the seepage characteristics and sensitivity analysis of a concrete face rockfill dam.The results show that the calculation results of seepage pressure,total head,hydraulic gradient and seepage velocity of the dam conform to the general law,and the calculation results of seepage flow are close to the measured values.The seepage flow is sensitive to both the panel and the curtain,and the seepage pressure of the dam foundation is significantly affected by the curtain permeability coefficient.The research results can provide reference for similar engineering calculation and analysis.
