【摘要】 鉴于水闸震害现象较为严重,分析了刚性地基模型、无质量弹性地基模型和人工边界模型的适用范围,并以某土基上的水闸为例,对比了不同地基模型对水闸动力反应的影响。结果表明,对土基上修建的水闸进行动力计算时应考虑土—结构相互作用和辐射阻尼效应的影响。更多还原

【Abstract】 Sluices have suffered serious losses caused by earthquake.Rigid foundation,mass-less foundation and artificial boundaries have been discussed and the suitability of these models has been pointed.Taking the sluice built on soil foundation as an example,the difference of dynamic response have been compared among the previous foundation models.It is suggested to take the soil-structure interaction and radiation damping into consideration for dynamic analysis of sluices built on soil foundation.更多还原
