Slope Seepage Stability Finite Element Analysis of Haimaqing Reservoir Clay Core Rockfill Dam

Considered the coupling effect of seepage field and stress field,taking clay core rockfill dam of Haimajing reservoir for an example,the displacement,stress and slope seepage stability of dam body at the normal water level case is calculated by using finite element method.The results show that under the normal water level,the stress and strain conditions of the embankment are satisfied so that the dam does not appear seepage failure;the stress-strain of core wall dam accords with the general laws;under the action of stable seepage,the safety factor of stability against sliding of the upstream and downstream dam slope meet the specification value,and the dam slope is stable.
