考虑流变效应的高心墙堆石坝应力变形分析

摘要

采用三维有限元法对某高心墙堆石坝的应力变形进行了计算分析，数值结果表明，大坝的应力变形值在合理范围内，基本稳定期的坝体沉降约占坝高的1.07%，该心墙堆石坝的位移及应力分布符合心墙堆石坝应力变形的一般规律。%Using the three-dimensional finite element method,the stress-deformation characteristics of a high core rockfill dam are analyzed. The numerical results show that the deformation and stress values are in a reasonable range and the dam settlement is about 1. 07% of dam height at the stable period. The stress-deformation characteristics are in accordance with the general rules of stress and deformation of core rockfill dams.
