摘要

基于集中力作用下的Mindlin解位移公式，推导得到均布荷载作用下的地基柔度系数，对地基上的四周自由板与地基共同作用进行简化计算，得出了考虑埋深时地基基础共同作用的解析公式。在基础板为刚性和弹性、荷载为集中荷载及均布荷载的情况下，对考虑埋深时的Mindlin解与不考虑埋深时的Boussinesq解的计算结果进行比较，表明，埋深比对于基础沉降、地基反力的分布、基础板的弯矩等都有一定的影响。给出了考虑埋深时的沉降修正系数公式，以供工程应用参考。

Abstract

Based on Mindlin displacement solution subjected to centralized load，the settlement coefficient subjected to uniform load is proposed. Simplifying the interaction between foundation with free boundary and ground soil

the formula of interaction taking into account interaction between foundation and subsoil is obtained. Considering the condition of rigidity or flexibility foundation plate

a comparison between Mindlin solution and Boussinesq solution results is made with the load condition of centralized load or uniform load. The results indicate that the depth ratio has an important influence

the results of foundation settlement

groundsill counterforce and the bending moment of foundation plate. The settlement coefficient considering depth ratio is presented; it can be referenced in practice.
