地下水池结构抗震概念分析与研究

地下水池通常存在于大型的地下污水厂、城市雨污水泵站、调蓄池等工程中。然而地下水池结构的抗震分析存在一系列难题,如设计理论的选取、流体作用力分析、构造措施的设计、设缝形式的影响等。介绍了常用的地下结构抗震设计理论,对地下水池结构存在的问题和抗震设计特点进行了分析和总结,并通过一系列案例提出了设计中的注意点,可供相似工程参考。

Analysis and Study on Structural Seismic Concept of Underground Tank

Underground tanks usually exist in large underground wastewater treatment plants,urban rainwater and wastewater pumping stations,storage tanks,etc.There are a series of difficulties about the seismic analysis in underground tanks,such as the selection of design theory,the analysis of fluid force,the design of structure measures,the impact of setting joint form,etc.The common seismic design theory of underground structure is introduced.The existing problems and seismic design characteristics of underground tank structure are analyzed and summarized.Based on a series of cases,the attentions are proposed for the design,which can be referred for the similar projects.
