摘要: 鉴于 GB 18306-2015《中国地震动参数区划图》将十三陵上水库工程区 50 年超越概率 10%的地震动峰值加速度由 0.15 g 调整为 0.20 g,相应地震基本烈度由7 度升至8 度。按照现行抗震规范,借鉴类似工程的坝料参数取值,结合筑坝材料的工程特性,并充分考虑大坝实际沉降情况下确定筑坝材料动力模型计算参数。采用拟静力法和非线性动力有限元法对上水库混凝土面板堆石坝进行了抗震复核。研究结果表明,上水库主坝抗震安全性能良好,满足规范要求。

Abstract: According to GB 18306-2015 Seismic Parameter Zoning Map of China, the ground motion peak acceleration with exceedance probability 10% over 50 years is adjusted the from 0.15 g to 0.2 g and seismic basic intensity is adjusted from 7 to 8 in Shisanling upper reservoir area. Based on current seismic code, referring to the parameters of damming materials for similar projects, combining the engineering characteristics of damming materials and fully considering the actual dam settlement, the calculation parameters of damming materials in dynamic model are determined in this paper. The quasi-static method and nonlinear dynamic finite element method are used for seismic review of upper concrete faced rockfill dam. The result shows that the seismic safety performance of the upper storage reservoir dam is good.

Key words: concrete faced rockfill dam, seismic review, nonlinear dynamic finite element method, stabilization
