本文用半解析元法分析了矩形基础与无限层土地基的三维动力相互作用,提出了一种新的半解析位移函数。采取在水平两方向解析,仅在竖向进行离散化的方法,使三维动力相互作用问题化为一维数值计算问题,大大减少了计算工作量和计算机内存,其计算可以在微机上实现。同时给出了有关基础计算的一些建议。
In this paper, the semi-analytical element method is used to analyze the three-dimensional dynamic interaction between a rectangular foundation and an infinite layer of soil, and a new semi-analytical displacement function is proposed. Taking the analysis in both horizontal directions and only discretely in the vertical direction, the problem of three-dimensional dynamic interaction is transformed into a one-dimensional numerical calculation problem, which greatly reduces the computational workload and computer memory, and its calculation can be implemented on a microcomputer. At the same time, some suggestions on basic calculations are given.
