摘　　要：为了确定柱下矩形扩展基础的底面尺寸,必须进行地基承载力的验算.以往一般采用试算确定基础的底面尺寸,试算的次数依经验而定.本文推出1种不需反复试算的数值逼近解法,通过手算在3步以内即可求得既满足规范要求又经济合理的基础底面尺寸.To determine the bottom area of the column＇s rectangle expanding foundation the checking computation of the ground＇s carrying capacity must be conducted; Usually, a trial-calculation is adopted to determine the foundation＇s bottom area and the times of the trial-calculation depends on experiences. This paper presents a numerical approximation method that does not require repeated trial and calculation,The bottom size of the base can be obtained by counting it within three steps by hand that meets the Code requirements and economically reasonable.
