| Abstract: | This article briefly introduces the stratified structural characteristics of Cemented Sand & Gravel Dam (CSG), studies the mechanics model and inherent relations of FEM analysis of CSG dam, and puts forward a continuum equivalent model to simulate the stratified structure of CSG. The authors apply strength reserve coefficient method and APDL technique to analyze the stress stability of CSG in static state. The result of calculation indicates that the CSG dam can meet stress stability requirement. |
