摘要
采用双参数地基模型来改进Winkler地基模型,并用有限差分法求解任意线荷载下的地基梁的微分方程,得到便于工程计算的线性方程组;通过变换参数和荷载,进一步研究参数和荷载对弹性地基梁挠度的影响,探讨地基与梁的共同作用的一般规律。采用双参数的理论较Winkler模型,计算较简便,也更符合地基受力、变形特点。
The double-parameter foundation model is used to improve the Winkler model, and the finite difference method is adopted to resolve the differential equation of the beam on elastic foundation under any linear load and linear equations that can be easily used in practical engineering are obtained. The influences of the parameters and the load on the deflection of the beam on elastic foundation are also studied. In comparison with the Winkler model,the presented model is more practicable,and the calculation is much simple.
