| 摘 要： | 通过对不同作用深度、不同长宽比矩形面积均布荷载角点下应力系数Mindlin解与Boussinesq解的分析比较，建立了二者之间的统计关系，利用“归一化函数”，引入“沉降计算深度修正系数”，并通过对北京地区数十个工程沉降实测值进行反分析得到“沉降计算经验系数”，提出了对不同埋深的天然地基与桩基都适用的“统一沉降计算公式”。

| Abstract: | By comparing and analyzing the distributions of Mindlin stress coefficient and Boussinesq stress coefficient under the corner of rectangular uniformly-distributed load with different buried depths and length-width ratio, the relationship between Boussinesq and Mindlin solutions is established statistically. The experiential coefficient for settlement calculation is obtained by back analysis on the measured settlement results of about sixties buildings in Beijing. An unified formula for settlement calculation characterized by a coefficient of correction for depth is proposed finally. The formula is suitable for the settlement calculation of both natural foundations and pile foundations. |
