| 摘 要： | 目前流行的双曲线冷却塔淋水构件基础的底板几乎均采用整体式底板形式，使得水池底板抗浮力计算工作量非常大，目前流行的设计方案均采用增加混凝土自重甚至采用增加抗拔锚桩的方案进行抗浮设计，也加大了工程成本。本文通过工程设计实例，介绍了分离式水池底板的设计方法，并与整体式进行比较和选择。分析后表明，分离式水池底板较目前流行的整体式底板具有良好的经济效益和安全保证。

| Abstract: | The popular supporting columns foundationslab for the natural draft cooling tower is aaopt the monolithic type which caused big uplift force, so the designer have to increase the foundation concrete dead weight or increase the anchor pile to resist this uplift force, and so that the cost is increased at the same time. In this article, with practical instances, the detail design of the separated foundationslab was introduced and compared with the monolithic type and selection. It＇s shown that the separate foundationslab have more economy and safety than the popular monolithic type present. |
