| 摘 要： | 针对Winkler弹性地基模型的不足,采用双参数地基模型。根据已有的Winkler弹性地基梁有限差分法,进行更进一步的公式推导,把微分方程转化为线性差分方程组,编制相应的通用计算机程序,可以得到不考虑广义剪力自由梁端的解答,通过改变参数进行大量数值计算,研究参数变化对地基位移及反力的影响,分析地基与梁共同作用机理,给出地基位移与反力的一般规律。

| Abstract: | In view of the shortage of the Winkler elastic foundation model, the double parameter foundation model is presented. Based on the finite difference method of Winkler elastic ground,calculus equations are transformed into linear differential equation group which is useful to the compilation of related general computer programms,and the solution of two ends of free beam can be obtained without respect to the general shear stress. Meanwhile, the normal rule of displacement and contact pressure can also be obtained through changing parameters associated with numerical calculation in large quantities to examine the effect on the foundation displacement and contact pressure, and analyzing the regulation of interaction of foundation and beam. |
