摘　　要：根据柱下单向偏心矩形扩展基础设计方法,利用基底最小反力Pkmin=0及3k≥0.85b的条件,给出了基础底面尺寸的直接计算方法。与现有计算方法相比,该方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 on base sizes is given in the article. It is deduced from the designing methods of rectangle spread foundation of single eccentric of sub-column and the conditions of the minimal anti-force of the base Pkmin = 0 and 3k ≥0. 85b. Comparing with the existing calculation, it can avoid repeatedly trial calculations and cubic equation and had economic, reasonable and simple advantages.
