摘　　要：根据柱下偏心矩形扩展基础设计方法,利用基底最小反力Pkmin=0的条件给出了双向偏心基础底面尺寸的直接计算方法.与现有计算方法相比,该法能避免反复试算和解一元三次方程,具有经济合理、计算简单的优点。The method of practical calculation of base sizes is given in the article. It is deduced from the designing methods of eccentric rectangular spread foundation under column and the conditions of the minimal anti-force of the base Pk min=0. Comparing with the existing calculation, it can avoid repeatedly trial calculations and cubic equation and has economic, reasonable and simple advantages.
