弹性矩型板与非线性地基共同作用的简化计算法

A non-linear concentrated spring model and its application

提出一种考虑地基非线性特性的地基模型 ,并把它应用到弹性板基础与非线性地基共同作用的分析中。计算结果表明 ,考虑地基非线性特性时 。

A nonlinear concentrated spring model is presented in this paper, and the model is applied to the analysis of elastic plate nonlinear subgrade interaction. The computation result shows that the subgrade reaction, the deflection and bending moment are improved greatly if the non linear property of subgrade is considered.
