根据《建筑地基基础设计规范》中关于地基承载力计算及软弱下卧层承载力验算的相关规定,文章推导出一种可直接计算出满足设计要求的基础底面积的简便计算方法。

Two groups of equations, which were used to calculate the foundation area of single-story granary, were given in this paper.

给出两组计算平房仓基础底面积的计算公式,分析按老规范进行偏心基础设计中因偏心距取值不当而出现的问题,同时根据新规范,以基础底面积最小为优化目标,针对影响基础偏心距的一些因素,分析在不同条件下基础偏心距对基础可靠度和经济性的影响,从而确定基础偏心距的合理取值。
