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。 Combined with the field test results, the mechanism of the interaction between the superstructure of the tall building and the sand foundation and the foundation of sand and gravel base is analyzed. The key problem of the interaction between the three is the solution of the reaction force of the foundation. For the first time, on the basis of the structural continuity method, Residual number method to find the size and distribution of the reaction force. The programmed factors were also used to quantitatively analyze the main factors affecting the size and distribution of the reaction force.
