By virtue of the design features of the mania dam , this paper studies the dynamic characteristics of the dam materials . by comparison with other similar projects , it presents a curve for dynamic characteristics of clay core materials and rockfill materials , makes analysis on the dam ' s plane dynamic response by finite element method , calculates the dam ' s seismic acceleration , the dynamic shear stress of the rockfill , and the dynamic stress of the cutoff wall in the overburden layer 本文针对满拉土心墙堆石坝的设计特点，进行了筑坝材料动力特性试验研究，通过与相关工程对比给出了心墙料和堆石料的动力特性曲线，采用有限元方法进行了大坝平面动力反应分析，计算了大坝的地震加速度、堆石体动剪应力及覆盖层防渗墙的动应力。
Through test and research of zipingpu reservoir concrete faced rockfill dam ' s material and finite element analysis of the dam , physics and mechanical characteristics were studied , such as characteristics of rock , compaction , permeability , compressibility and so on , of the no viscous moraine and gravel . at the same time , the mutual relation of physics and mechanical characteristics were studied 对紫坪铺面板堆石坝筑坝料试验研究，了解堆石料等无粘性粒状土的岩性、级配、压实性、渗透性、压缩性等物理力学性质，以及物理性与力学性之间的相互关系。
