摘　　要：山地地区高差极大,水处理构筑物需架空才能满足工艺布局。文中结合实际工程,对水池池体与高架平台采用油毡隔离方案及直接放置方案进行对比,采用midas Gen有限元软件对高架平台及构筑物整体建模进行时程分析计算,得出采用两种方案的优势与不足,最终选择直接放置方案。而后,对高架平台及构筑物整体建模进行受力分析,得出此类地震作用下结构受力及变形特点,为以后类似工程设计提供参考。The water treatment structure needs to be elevated to meet the process layout in mountainous areas with great elevation difference.Combined with a practical engineering,using the finite element software Midas Gen for overall modeling and time history analysis,advantages and shortcomings of two schemes were compared.In the first scheme,water tank was isolated from elevated platform by roof felt.In the second scheme,water tank was directly laid on elevated platform.Analysis results proved that the direct placement scheme was recom-mended.At last,the stress and deformation characteristics of this kind of structures were analyzed with overall modeling of structures with elevated platforms.The research can provide reference for similar engineering design in the future.
