摘　　要：预应力技术的应用可以有效解决超高水池结构体系不合理导致的壁厚设计过大、配筋过大,以.及无法满足水池抗裂度要求和超长结构的温度伸缩缝问题。本文结合工程案列,通过合理选择结构受力体系并采用有粘接预应力技术对大型矩形水池中预应力钢铰线的配置进行估算,解决了地上式水池的抗裂问题以及超长设缝问题。The application of prestressing technology can effectively solve the problems of excessive wall thickness,excessive reinforcement,failure to meet the requirements of cracking resistance and temperature ex-pansion joints of super-long structure caused by unreasonable structural system of super-high water pool.In this paper,reasonable structural stress system was selected.Combining with bonded prestressing technology in a large rectangular pool confiquration of steel strand was estimated.The problem of anti-cracking and setting su-per-long joints for the above-ground pool was solved.
