摘要

关于矩形水池的结构计算,目前在实际工程中多考虑采用简化的计算方法,即采用近似的弯矩分配法,并将水池底板的地基反力视为线性分布,这种方法显然不够合理。本文对近年来国内外出现的一些较为精确的计算方法进行归纳总结,并简要分析各种方法或研究成果的应用情况。这些方法已考虑水池各板块的相互作用和弹性地基对水池的影响等问题,但还需继续完善与推广。
Concerning the calculation of the cistern structure,a simplified method is usually adopted in practical projects at present,that is approximate moment distribution method considering the reaction of the bottom plate as the form of linear distribution.Apparently,this method is not quite reasonable.Some of the more accurate calculation methods in recent years both at home and abroad are summarized in this paper including a brief analysis of various methods or research applications.The interaction between cistern plates and the influence of elastic foundation's to cistern have been considered in these methods.However,the research need to continue to be improved and promoted.
