摘要
本文主要研究用边界元方法分析土中刚性结构的阻抗和动力反应。文中给出了箱形结构和圆形结构情形的土壤阻抗以及箱形结构在地表简谐压力和三角形脉冲压力作用下的动力反应的数值结果。为了运用边界元方法,文中的前半部对于奇异性、角点、特殊函数的计算以及离散化等几个问题也进行了讨论。
The present paper deals primarily with the solution of the soil impedance and the dynamic response of buried-rigid structures by using the boundary element method. Results of numerical calculation are given, including the soil impedance for rectangular and circular cylindrical inclusion conditions and dynamic response of buried-box structure to harmonic and impulsive loading acting on the ground surface.For the application of the bonndary element method in the first part of the paper, some problems, namely the singularity, the treatment of the corner point, the computation of the special functions and the discretization are discussed.
