摘　　要：提出一种上部结构有限条法、地基（土）特解边界元法相结合的半解析方法，首次建立了这一力学模型在频域内的运动方程，并编制了求解结构－地基动力相互作用的程序。通过计算有关算例，并与ＳｕｐｅｒＳＡＰ程序计算结果进行比较，证明本文的基本理论和计算程序是正确、可行的。The paper presents a method, or Semi Analytical Element Method which marries the Finite line in the upper structure with the Special Boundary Element Technique in the soil. The equation of motion to this dynamic mathematical model in the frequency domain is first established. The paper designs the computer program and calculates the actual problem. Compared the calculated results of the program SSAP with those of it, this paper′s theory and computer program are proved to be right and practicable.
