L为桩长，r为计算点与桩轴线的水平距离，z为计算点距离地面深度。都取正值

％f1,f2,f3依次是点荷载、均布荷载以及三角形荷载下的Geddes应力解函数

％Ip,Ir,It依次是对应三个荷载下的应力系数，负表示拉，正表示压-pile length L, r points and to calculate the pile axis horizontal distance, z to calculate the distance depth of the ground. Take the positive% f1, f2, f3 followed by point load, Loads and loads of triangular Geddes Stress Solution function% Ip, Ir, It followed three counterparts under the stress load factor, the negative said Rafah is said pressure
