地下结构浮力计算方法分析

Analysis of Buoyancy Calculation Method of Underground Structure

本文以地下粮仓为研究对象,按照阿基米德定律进行浮力计算,通过配重法分析,得出在地下水作用下,地下粮仓浮力影响大的结论;文章结合地下粮仓的地质情况及相关规范,认为应将浮力计算的水-仓模型调整为水-土-仓算模型,为以后地下粮仓抗浮设计研究提供参考。

In the paper a brief analysis of buoyancy calculation method of underground structure is done,and underground granary is taken as the research object.According to the Archimedes law carries on the buoyancy calculation,the weight matching method analysis is used.It is concluded that the buoyancy of underground granary has great influence under the action of groundwater.Based on the geological conditions and relevant norms of the underground granary,the water-soil model of buoyancy calculation should be adjusted to the water-soil-silo model.It provides some reference for the design of the underground granary anti-flotation design in the future.
