本文根据P-Y曲线,应用差分法计算横向荷载桩的内力和位移。该法不需要求解大型联立方程组,可一次求解。计算实例表明,采用本文法的计算结果和其它方法的计算结果是一致的。 Based on the P-Y curve, this paper calculates the internal forces and displacements of the laterally loaded piles by using the difference method. This method does not need solving large simultaneous equations and can be solved once. The calculation example shows that the calculation results of this method are consistent with those of other methods.
