摘要

精细积分法是求解结构动力响应问题的一种高精度算法，将其应用于地基震动响应问题的求解。在不影响算法精度的前提下，采用节省存储量的矩阵向量乘法和精细积分级数解，降低了精细积分法的存储需求。开发了地基震动响应分析程序，并对一重大工程的建筑地基进行了震动响应分析，通过与著名有限元分析软件Nastran的计算结果进行对比，证明前述方法和程序是正确的。

Abstract

The precise integration method is a high precision algorithm for structural dynamic response. The method is applied to foundation vibration response. In order to reduce storage requirement

matrix-vector multiplication that saves storage

and series solution are adopted; moreover

the precision of precise integration method isn’t affected. A corresponding program is developed for analysis of foundation vibration response. A building foundation of an important project is analyzed. The results are compared with the results of Nastran

a famous finite element analysis software; and correctness of above-mentioned methods and program is validated.
