【摘要】 以往土石坝在强震中曾遭受过严重的震害，满拉水利枢纽工程土心墙堆石坝建立在高烈度区的土石坝，因此，了解和掌握满拉大坝的抗震性能是非常必要的。 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。通过对计算结果进行分析认为满拉土心墙堆石坝具有较强的抗震性能。更多还原

【Abstract】 The earth dam had in the past usually been under severe impact during violent earthquakes. The rockfill dam with clay core in Mania Multi-Purpose Water Project is constructed in high intensified areas, it is therefore imperative to have a thorough knowledge about the earthquake resistance of the dam.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. Through analyzing the above calculation results, it is believed that the Mania rockfill dam with clay core is highly capable of earthquake resistance.更多还原
