一、前言 泄水闸是水利工程中的重要建筑物,具有挡水及泄水的双重作用。解放以后,为了防洪、灌溉、排涝、航运以及挡潮等目的,我国在黄河、长江、淮河、海河等流域及其它许多地区建立了数以千计的大、中型水闸和小型水闸,促进了工农业生产的不断发展,给国民经济带来了很大的效益。 然而,我国是多地震国家,地震活动频繁,给许多水闸造成了严重的震害。例如,在河北省唐山地震中,据调查唐山地区经受6度以上(包括6度)地震的水闸有80％遭到不同程度的破坏。从而引起水利工作者对泄水闸体系防震的重视,对其防震设计提出了若干规定。但是
First, the foreword Sluice gate is an important building in water conservancy project, with the dual role of retaining and discharging. After the liberation, thousands of large and medium-sized sluices and small sluices have been set up in the Yellow River, the Yangtze River, the Huaihe River and the Haihe River and other drainage areas in order to prevent floods, irrigation, drainage, shipping and tidal flats. The continuous development of agricultural production has brought great benefits to the national economy. However, our country is a multi-earthquake country with frequent earthquakes and caused serious damage to many sluices. For example, in the Tangshan earthquake in Hebei Province, 80% of the floodgates that were subjected to earthquakes of 6 degrees or more (including 6 degrees) in the Tangshan area were investigated to varying degrees. As a result, water conservancy workers are attaching great importance to the earthquake proofing of the sluice system, and some provisions are put forward for its shockproof design. but
