【摘要】 结合工程实际,在考虑地震动水压力作用与地基弹性影响的基础上,提出了空间悬臂梁水闸结构分区规则,导出了悬臂梁柔度计算公式.利用该计算方法对大涧河水闸进行了抗震计算,得到了水闸结构的自振频率及底板应力,并与商业软件MSC.MARC的计算结果进行了比较.结果表明,2种方法的计算结果较为一致.这说明本文提出的水闸结构抗震分析方法是合理的,可以应用于大中型水闸的抗震分析.更多还原

【Abstract】 Based on practical engineering experience,zoning principles for spatial cantilever-based sluice structures are put forward with consideration of the effects of seismic hydrodynamic pressure and foundation elasticity.A formula for cantilever flexibility is proposed.The seismic response of Dajianhe Sluice was calculated using this method.The natural vibration frequencies of the sluice structure and the stress on the bottom plate were obtained and compared with the results calculated with the commercial software MSC.Marc.The results show that the two models agree well,and the present method is feasible and can be applied in the seismic analysis of medium-size and large sluices.更多还原
