埋地储罐抗浮性能分析与评估

An Analysis and Checking on Anti-floating Capability of Buried Storage Tank

通过分析埋地储罐在不同覆土状态下所受的浮力和覆土重力，对几种常用规格埋地储罐的抗浮能力以及影响抗浮性能的因素进行了分析比较，指出了使用现有抗浮计算公式存在的问题，提出埋地储罐的抗浮验算新方法，并说明了工程中常用的埋地储罐抗浮措施。

In this article is given the anti - floating checking computation on the floating force and gravitation of underground tank and covering earth. The anti - floating conditions of tanks in several cases are discussed by analyzing the main factors. Based on the result of anti -floating analysis in detail, a new correct method is proposed while the former method＇s incompleteness is pointed. And also the new method for anti - floating checking calculation is shown by the example in which the anti - floating measurement are provided by calculating the size of the anti - floating substructure or the burying depth of the settled underground tank.
