【摘要】 计算了无覆盖层与不同厚度覆盖层上土石坝地震响应,并对比了土石坝的加速度分布规律,分析了不同厚度覆盖层对大坝加速度反应的影响。结果表明,覆盖层对地震加速度的分布与峰值均存在不可忽略的影响。更多还原

【Abstract】 This paper calculates seismic response of earth-rockfill dam on rock and different thickness of overburden foundation,compares their acceleration distribution law.And then it analyzes the influence of acceleration response of dam on different thickness of overburden.The results show that the influence of overburden on earthquake acceleration distribution and peak cannot be ignored.更多还原
