In geotechnical [[civil engineering]], the '''p-y method''' is a method of analyzing the ability of [[deep foundations]] to resist loads applied in the lateral direction. This method uses the [[finite difference method]] and p-y graphs to find a solution. P-y graphs are graphs which relate the force applied to [[soil]] to the lateral deflection of the soil. In essence, [[non-linear]] [[spring (device)|spring]]s are attached to the foundation in place of the soil. The springs can be represented by the following equation:
 
: <math> p = ky </math>
where ''k'' is the non-linear  spring stiffness defined by the p-y curve, ''y'' is the deflection of the spring, and ''p'' is the force applied to the spring.
 
The p-y curves vary depending on [[soil classification|soil type]].
