| 摘 要： | 从实测的P-S曲线（基地压力与沉降的关系）出发，将P-S曲线拟合成分段线性函数，把分段线性函数的斜率作为基床系数，推导出变基床系数弹性地基梁的基本理论方程式，并将它变换成与常基床系数弹性地基梁相同的方程形式，从而，可以用初参数法解出它的一般解。此方法可以推广到变截面梁和非均质地基的情况。

| Abstract: | Based on actual measured P-S curve, this article fits the curve to subsection linear function, and uses the slope of the function as bedding value. Then it derives the basic academic equation of variable bedding value elastic foundation beam; and changes it to the same equation form as constant bedding value elastic foundation beam. Having done that we can get the common results using the initial parameter method. This method can also be used in the case of variable cross-section beam and heterogeneous foundation. |
