大跨度水池底板及池壁受力分析

Stress Analysis of Large Span Pool Floor and Wall

大跨度水池结构的形式看似简单,涉及构件较少,很多敞口水池实际上只涉及底板和池壁的设计,但实际上由于跨度较大,有一些项目的池深较深,再加上水池结构属于特种结构,很多结构工程师在水池结构设计上的经验不足,可参考的资料少、旧,并且针对特殊情况没有可参考性。列举一个工程实例中的大跨度水池,利用SAP 2000有限元软件,分析该水池的受力特点,并针对可能影响池壁及底板受力的各种因素做定性分析,为类似工程提供可参考的设计思路。

The form of large-span pool structure seems simple,involving fewer components.Many open water tanks actually only involve the design of bottom plate and pool wall.However,due to the large span,some projects have deeper pool depth.In addition,the pool structure belongs to special structure.Many structural engineers have insufficient experience in the design of pool structure,and the reference materials are few and old,and there is no reference for special cases.This paper lists a large-span pool in an engineering example,analyzes the mechanical characteristics of the pool by using SAP 2000 finite element software,and makes qualitative analysis on various factors that may affect the force of pool wall and bottom plate,so as to provide reference design ideas for similar projects.
