复杂场地下多工况组合式水池的结构设计要点与分析

Key Points and Analysis of Structural Design of Multicondition Combined Pool in Complex Geologic Environment

以华南地区某新建自来水厂的组合式调节池结构设计为例,在边坡支护结构方案中提出复杂丘陵地形建厂的影响要素和设计原则,在水池多工况结构分析中提炼设计要点并对比了三维有限元分析计算法与单构件简化计算法的差异,在构件布置中提出了适用于大跨度水池结构的优化构造。本研究提出的复杂场地下多工况组合式水池的结构要点和分析,兼顾安全性、可行性、合理性和经济性,为后续类似给排水工程水池结构设计提供一定参考。

The structural design of a combined regulating pool for a new waterworks in South China was taken as an example.For building a plant on complex hilly terrain,the slope support structure scheme,which considering the influencing factors and design principles were presented.In the pool structure analysis under multiple conditions,the key points were extracted,and the difference between three-dimensional finite element analysis calculation method and single component simplified calculation method was compared.In the compo-nent layout,an optimized structure suitable for large-span pool structures was proposed.This study introduces the key points and analysis of structural design of multi-condition combined pool in complex geologic environ-ment,which takes the safety,feasibility,rationality and economy into account.And the results could provide a certain reference for the following similar pool structure design of water supply and sewerage engineering.
