关于各种弹性地基模型上的结构分析

Structure Analysis of Various Elastic Subgrade Models

地基模型一般可分为:(1)Winkler 模型,(2)Boussinesq 半无限体模型,(3)成层模型,(4)双参数模型,(5)各种非弹性(如粘性、塑性)模型等。(1)～(4)属于弹性地基模型.本文首先分析了各种弹性地基模型,然后综述了近年来国内外发表的有关置于各种弹性地基模型上的结构分析方面的成果,文中也包括作者自己尚未发表的部分成果。

Subgrade models are generally divided into (1) Win'kler model,(2) Boussineuq's model of halfspaee continuum,(3) layered model,(4) two—parameter model and (5) non-elastic models(such as adhesive and plastic).Models (1)-(4) belong to elastic foundations.The paper firstly analyzed various elastic subgrade models and then surveyed the results of struc- ture analysis about various elastic subgrade models published in recent years both in China and abroad,including the unpublished results by the author himself.
