根据修正的双参数法求解桩基的水平内力

Solution for Horizontal Internal Force of Pile Foundation by Revised Dual Parametric Method

近年来关于桩基水平内力的研究已取得一系列新的成果,虽然采用多种方法计算的基桩水平内力与实测值比较接近,但其计算过程比较复杂,采用的计算参数多由土工试验得出,受人为因素影响较大。为进一步简化桩基水平内力计算并提高计算精度,根据修正的双参数法和有限差分原理推导桩基水平内力的计算公式,可求得桩身各节点的水平内力。

For recent years, a series of fruits are gotten in the research on the horizontal internal force of pile foundation. The horizontal internal forces calculated by different methods are close to the measured value, but those calculating processes are very complex and the adopted parameters are obtained in soil experiment, which may be greatly affected by man-induced factors. In order to simplify the calculation for the horizontal internal force of pile foundation and improve the accuracy, the revised dual-parametric method and the finite difference principle are adopted to deduce the formula for the horizontal internal force of pile foundation, by which the horizontal internal forces on each nodal points of pile can be obtained.
