An Analysis Framework of Stability for the Concrete Gravity Dam in Landfill

The dam stability is vital to the landfill safety, and its design and analysis generally refer to several relevant specifications. Therefore, taking the concrete gravity dam of a typical landfill project in Hangzhou as the background, both limit equilibrium method (LEM) consisting of two simplified calculation modes and strength reduction method (SRM) are adopted to analyze the dam stability. The calculation models are simplified and the resulting ultimate sliding surfaces are similar to each other. The safety factors are 1.474 and 1.469 in the LEM, respectively. However, it is 1.23 in the SRM. The difference can be due to the different calculation mechanism. Considering some actual construction factors, the dam could be identified in a stable state. Finally, the analysis framework of the concrete gravity dam in a landfill is expected to be a reference for similar projects.
