根据弹性地基上的半无限平面理论，利用计算弹性地基梁的链杆法，将地基的弹性刚度矩阵与上部结构刚度矩阵相协调、综合，引进上部结构与地基土的综合刚度矩阵，解决了结构与土的相互作用问题，计算方法简单、实效．
According to the semi-infinite plane theory on elastic foundations, the elastic struts of the elastic foundations are used to calculate and synthesize the elastic stiffness matrix of the foundation and the stiffness matrix of the superstructure, and the integrated stiffness matrix of the superstructure and the foundation soil is introduced to solve the structure. Interaction with soil, the calculation method is simple and effective.
