Safety analysis of cemented sand and gravel dam considering different stress levels

The overall security and stability of cemented sand and gravel dam are better by using thesymmetric trapezoidal profile, but the toe and the foundation of the dam are fragile. In order to analyzethe safety of cemented sand and gravel dam, the stress of a cemented sand and gravel dam with 100 m inheight and the comparison with gravity dam are analyzed under three water levels. And the anti-shearand anti-sliding stability analyses of these two dams are carried out by introducing the stress level andpoint safety factor method. The results show that the safety of cemented sand and gravel dam is betterthan the gravity dam with the same elevation, the stress is less affected by water load, the stress level dis-tribution is more reasonable and the safety factor is higher under the same foundation conditions.
