摘要
首先提出多变参数修正迭代法，且用此法研究了非线性弹性地基上圆板在均布载荷作用下的大挠度问题，求得了精确度较高的二次解析解，与线弹性地基上圆板的大挠度进行了比较，完全吻合了物理意义，工程中可参考应用．
An iteration method with multiple variable parameter correction is presented first. Then the large deflection problem of circular plate fixed on nonlinear elastic foundation and subjected to uniform load is investigated by using this method and an analytic solution of degree 2 with higher accuracy is obtained. Compared to the solution of the same problem but with linear elastic foundation, it is found that the solu- tion obtained has reasonable physical meaning and could be taken as a reference in engineering.
