摘　　要：《建筑地基基础设计规范》中采用的柱下矩形单向扩展基础底板弯矩的计算方法是一种精确的方法,由于其运算繁琐且仅有单向偏心情况下的计算方法,故在用其进行手工快速较核和施工图审查时会带来很大的不便。简易近似算法不仅能进行单向偏心矩形扩展基础底板弯矩的近似计算,而且能进行双向偏心矩形扩展基础底板弯矩的近似计算,公式简单且使用方便、快捷,通过它的运用将给工程设计人员和施工图审查人员带来很大的方便。The calculating method of base slab＇s bending-moment for column＇ s one-way eccentric rectangular spread foundation, which is adopted in Code for design of building foundation GB50007-2002, is a precise method. But it will bring much trouble in quickly hand-proofreading and checking construction drawings, because of the complex calculation and special requirement. In this article, we introduce a simple and approximate method for calculating base slab＇s bending-moment of not only one-way but also biaxial eccentric rectangular spread foundation. The method is easy, convenient and speedy. It can help designers and checkers working easier.
