摘　　要：从一个具体水闸的抗震分析出发 ,讨论了水闸抗震的一些问题。在实际设计工作中 ,水闸通常按一维结构——悬臂梁进行分析 ,文章则对水闸进行了详尽的二维计算。从分析结果可以看出 ,二维计算才能真实地反映出水闸单墩的模态特性 ,并且水闸扭振的影响是不可忽略的。文章还对这个典型的水闸 ,给出了各种振型图及响应结果 ,可供有关设计部门参考。In this paper a case study is made of the seismic resistance of sluice.In practical design, the buttress of the sluice is usually considered as a cantilever.In this paper the sluice is minutely analyzed in lightof two dimensional structure.The calculated result indicates that the two dimensional analysis can really reflect the modal characteristics of the sluice,and the effect of the twist vibration of the buttress cannot be neglected.Graphs of various vibration types and responses of the sluice are given for a reference of related designers.
