doi:10.3969 /j.issn.1674-0696.2013.02.24

Abstract

Abstract: Based on the equivalent linear model，3-D nonlinear dynamic finite element method is used in seismic dynamic response analysis of Jinfo Mountain CFRD ( Concrete Faced Rockfill Dam) . The response of acceleration，dynamic stress，the regular pattern and distribution of permanent deformation under seismic loads are studied. The results show that the downstream slope near the crest has larger acceleration response，it should be taken appropriate anti-seismic engineering measures; the reaction of dynamic stress and dynamic shear stress for dam body is very little; and the permanent deformation for dam body is not large. The overall anti-seismic performance of the dam is good enough to meet the anti-seismic stability requirements under the given earthquake.

Key words: concrete faced rockfill dam, equivalent linear model, 3-D dynamic analysis, permanent deformation, Jinfo

摘要： 基于等效线性模型，采用三维非线性动力有限元法对拟建金佛山混凝土面板堆石坝进行了地震动力反应分析，重点研究了坝体在地震荷载作用下的加速度反应、动应力反应、地震永久变形的规律和分布。计算结果表明: 坝顶附近加速度反应较大，应采取相应的抗震工程措施; 坝体动应力反应较小; 坝体残余变形不大; 大坝整体抗震性能较好，满足给定地震下的抗震安全性要求。
