Study on slope stability of earth rockfill dam in the reinforcement process of building cut-off wall
Concrete cut-off wall is widely used in the reinforcement project of earth rockfill dam.In order to analyze the influence of cut-off wall on dam slope stability, it is established a finite element numerical model coupling both the seepage and stress field, so as to enable the calculation of factor of safety of dam slope stability and to compare the differences before and after the reinforcement using strength reduction finite element method.Research shows that under normal storage conditions, the safety factor of downstream dam slope increases significantly after building cut-off wall while it reduces slightly for the upstream dam slope.
