摘要
采用邓肯-张E~μ模型对EDG水库大坝进行了三维非线性有限元静力分析,通过对沥青混凝土心墙坝的应力与应变分析,研究满蓄期砂砾料坝体的应力、位移分布。结果表明：大坝变形量值和分布规律基本合理,应力应变均在合理范围,大坝安全稳定。
3D finite element static analysis was conducted with the Duncan-Chang model for the main dam of EDG Reservoir. Based on stress and strain analysis of the asphalt concrete core wall dam, the stress and displacement distribution of sand gravel dam body under full impoundment was studied. The results of study demonstrate that main dam is safe and stable with deformation value and distribution rule being rational, stress and strain within acceptable range.
