摘要
本文应用了模糊数学的概念和变基床系数法,将文克尔和弹性半无限体模型有机地结合为一体,能计算包括这两种极端状况(完全忽略或夸大应力-应变扩散能力)在内的任何地基状态。由于考虑了地基实际变形特征使得计算结果与实测结果能较好地符合。该方法计算简便,并且不需更多的计算参数,从实际工程的设计已证明该方法具有经济性和安全性。
In this paper,the conception of fuzzy mathematics and the method of changeable modulus of subgrade reaction have been used to integrate organically the Winkler model with the elastic half-space model.This method can be used to calculate any subgrade states including two extreme states:the Winkler state and that of the elastic half-space ( the former has entirely neglected the ability of spreading of stress-strain of soil, while the latter has exaggerated its ability),As the actual deformation characteristics of soil have been considered, the results of calculation agree well with those of field measurements. The merit of this method is its simplicity in calculation with less calculating parameters needed. It has also been proved by actual engineering designs that this method is safe and has economic effect.
