超长无缝多层水池结构温度影响分析

Analysis of Temperature Influence on Super-long Multi-story Tank without Joint

基于有限元方法,研究了超长无缝多层水池结构设计时应考虑的温度作用。首先探讨了水池结构设计时所涉及的温度作用,分析了地上水池在温度作用和池内水压力作用下的内力分布特点,总结了超长无缝多层水池的结构设计要点。结合工程案例,分析了不同结构方案下池壁在温度作用和池内水压力作用下的内力,并进行了对比研究。根据分析结果,针对超长无缝多层水池在结构设计时所需考虑的温度工况以及结构方案优化提出了若干建议。

Based on finite element method,the temperature effect on the structural design of multi-story su-per-long tank without joint was researched.The temperature effect patterns of structural design was investigated,and the internal forces distribution characteristic of poll wall under temperature effect and hydraulic pressure were analyzed.The key points of structural design under ultimate limit states and serviceability limit states were summarized.Combined with actual engineering case,the variation of the internal forces among different struc-tural layout schemes was analyzed.According to the analysis result,some proposals were provided for tempera-ture effect and optimization of structural layout.
