摘　　要：结合工程实例,对加隔墙改造前后的现状多格水池构筑物进行了基于Winkler假设有限元建模分析,将底板内力计算结果与工程设计计算中的净反力直线分布假设的计算结果对比。针对上述成果,分析了两种假设计算的优缺点,给出了改造前后不利工况下弯矩包络结果。Combined with engineering examples,a finite element modeling based on the Winkler assumption of the multi-grid pool structures with adding partition walls was analyzed.The results of this analysis are compared with the calculation results of the linear distribution assumption applied in the engineering design.In view of the above results,the advantages and disadvantages of the two hypothetical calculations are analyzed,and the bending moment results under dangerous conditions are shown.
