摘　　要：《建筑地基基础设计规范》GB50007-2011中采用的柱下矩形单向偏心扩展基础底板弯矩的计算方法是一种相对精确的方法,同时也是一种繁琐的方法.本文提出了一种不需要计算基底反力而直接利用柱脚内力计算基础底板弯矩的计算方法,该方法适用于中心受压、单向偏心受压及双向偏心受压等所有受力情况.通过算例比较,其计算结果与规范算法差别极小.The calculating method of base slab’s moment for the column’s one-way eccentric rectangular spread foundation,which is adopted in Code for design of building foundation GB50007-2011,is an exactly and tedious method.In this article we introduce a method for calculating base slab’s moment of column’s which use the internal force of the column’s bottle directly,It is not necessary to calculate the basal reaction,The method is suitable for all rectangular spread foundation about center compression and one-way eccentric and double-way eccentric compression.By means of the comparison by an example the calculation result is very close to the calculation result from the Code.
