摘要
针对CSG坝成层的结构特点,对CSG坝有限元分析的力学模型及本构关系进行了分析探讨,提出了连续等效模型模拟层状CSG结构;应用强度储备系数法和APDL技术,对静力状态下的CSG坝的应力稳定进行分析。分析结果认为,大坝满足一定的应力稳定要求。
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.
