The value of the load directly undertaken by the soil depends upon the pile depth, pile spacing and physical and mechanical properties of the soil.
土直接承担外荷载的大小与桩距、桩长和土的物理力学性质有关。

The axial load and centralizer spacing from the bottom to the top are calculated by using the mechanical analysis method and the well trajectory data.
采用力学分析的方法，结合井眼轨迹数据，由下到上逐跨计算了抽油杆柱的扶正器间距和轴向力。

The influences of pipe net spacing distance, pipe diameter, buried depth and soil's Poisson ratio on the distribution of superimposed load are discussed.
