摘要

通过对"5.12"汶川地震震区水闸震害调查资料以及其他水闸震害文献资料进行统计分析,讨论了水闸结构震害特点;对水闸震害的规律进行了分析,探讨了水闸的新震害趋势;之后对水闸抗震设计分析中的计算模型、地震动输入、特殊荷载(动水压力、闸门往复力、冰荷载)及相应荷载组合等问题进行探讨,结合现行水工建筑物规范对水闸抗震设防的要求,总结了水闸的抗震构造措施。
Through the statistical analysis on the data of the investigation on seismic damage of sluice structure within the seismic area of 5.12 Wenchuan Earthquake and the other relevant literatures of the seismic damage of sluice,the characteristics of seismic damage of sluice structure is discussed herein,while the law of the sluice seismic damage is analyzed and the new trend of the seismic damage upon sluice is explored.Hereinafter,the calculation model,the ground motion input,the particular loads(dynamic water pressure,reciprocation force of sluice gate,ice load) and the relevant load combinations in the analysis of the seismic design of sluice structure are also probed.Combined with requirements for seismic resistance on sluice structure from the existing specifications for the design of hydraulic structure,the construction measures for seismic resistance of sluice are summarized as well.
