Method for calculating soil pressure borne by slide-resistant pile by considering horizontal soil arching effect
The invention discloses a method for calculating soil pressure borne by an anti-slide pile by considering a horizontal soil arching effect. The method comprises the following steps: calculating preconditions; assuming the shape of a soil arch; determining a calculation section and related parameters; determining the physical and mechanical properties of the potential sliding surface and the rock-soil body; and calculating the landslide thrust. The method has the beneficial effects that the shape of the horizontal soil arch and the change rule of the shape in the pile length direction are considered, and the calculation precision of the landslide thrust borne by the anti-slide pile is improved; a horizontal soil arching effect is considered, so that the soil arching effect is applied to engineering practice, and the defects of a traditional landslide thrust calculation method are overcome; the landslide thrust calculated by considering the horizontal soil arching effect is more practical, and meanwhile, the calculation result is beneficial to size design, material selection, pile design scheme selection and the like of the anti-slide pile.
本发明公开了一种考虑水平土拱效应的抗滑桩所受土压力计算方法，包括如下步骤：计算前提条件；土拱形状假定；确定计算截面及相关参数；确定潜在滑动面和岩土体的物理力学性质；滑坡推力计算。本发明的有益效果：考虑了水平土拱形状以及形状沿桩长方向的变化规律，提高了抗滑桩所受滑坡推力的计算精度；考虑了水平土拱效应，使土拱效应应用于工程实践，弥补了传统计算滑坡推力计算方法的不足；考虑水平土拱效应时计算的滑坡推力更符合实际，同时此计算结果利于抗滑桩的尺寸设计、材料选取、桩设计方案的选择等。
