[提要]  结合现场实测结果分析了高层建筑上部结构与箱基和砂卵石地基共同作用机理，对三者共同作用的关键问题——基底反力的求解，首次在结构连续化方法的基础上，运用加权残数法求出了基底反力的大小及分布。还运用所编程序定量分析了影响基底反力大小及分布的主要因素。

Based on results of field measurements, the mechanism of interaction between high-rise building super-structure, foundation and cobble-stone subsoil is discussed. For calculation of subsoil reactions which is the critical problem of interaction between high-rise building superstructure, foundation and cobble-stone subsoil, the weighted residual method is first used to calculate value and distribution of subsoil reactions on the basis of structural continuum. The program for calculating subsoil reactions is coded in FORTRAN and quantitative analysis of a variety of influencing factors which affect value and distribution of subsoil reactions are carried on.
