Rock and Soil Mechanics
The concrete cutoff wall is the main anti-seepage structure of the rockfill dam resting on the deep overburden foundation, and is the key to ensuring the dam safety. Therefore, it is of great significance to accurately simulate the stress state of cutoff wall for evaluation of the rockfill dam resting on the deep overburden. Combining the incremental iteration method and the finite element-scaled boundary finite element coupling method (FEM-SBFEM), this paper realizes the trans-scale refined numerical analysis of the stress and deformation of the rockfill dam, which overcomes the low precision of the conventional midpoint increment method in solving local …
