根据规范公式并结合工程实际情况，对偏心荷载下基底反力的影响作了理论分析，结果表明，单方向增大基础尺寸，可以产生较大的基础边缘压应力，有可能对基础产生不利的影响，因此，在地基基础设计中，不可以单方向随意加大基础尺寸或根据面积等同原则改变基础位置，而应该按照实际偏心情况验算地基承载力。%According to the normal formula and combining with the engineering actual situation,this paper made theoretical analysis on basement reaction influence under eccentric load,the results showed that,the increasing of single direction base size,could produce large base edge com-pressive stress,could cause adverse effect to possible foundation,therefore,in foundation design,could not single direction to increase the size or according to area equivalent principle changed fundamental settings,and should be in accordance with the actual eccentric situation calculated the foundation bearing capacity.
