    • A finite difference analyzing method of a pile is provided to consider a lateral flow quantity as well as a lateral flow pressure based on a non-linear subgrade reaction theory capable of reflecting non-linearity of soil. One mathematical formula considering the lateral flow pressure or another mathematical formula considering the lateral flow quantity is selected as a finite difference model of the pile constructed in the soil(110). The lateral flow pressure or quantity, a length, diameter, bending stress, a boundary condition for a pile head and tip are inputted to the selected mathematical formula(120). A subgrade reaction coefficient for each component is calculated by considering cohesive soil, multilayer soil, and depth of the ground, and at least one of horizontal displacement, inclination, bending moment, and shear force of each component is calculated(150).
    • 根据能反映土的非线性的非线性路基反力理论,提出了桩的有限差分分析方法,以考虑横向流量和侧向流压。 选择考虑横向流动压力的数学公式或考虑侧向流量的另一数学公式作为在土壤(110)中构建的桩的有限差分模型。 选定的数学公式(120)中输入侧向流压力或量,长度,直径,弯曲应力,桩头和尖端的边界条件。 通过考虑粘性土,多层土和地面深度来计算每个分量的路基反应系数,并且计算每个分量的水平位移,倾角,弯矩和剪力中的至少一个(150)。
