The sand p-y curve methods were adopted by the new and old standard of American Petroleum Institute(API),which were the two most widely used methods.At present,the new API method is directly adopted by our country’s Code for pile foundation of harbor engineering(JTJ 254―98).The two p-y curve methods were compared and analyzed in theory.Combining with an engineering pile test with good measurement data,the two p-y curve methods and engineering example were compared and analyzed by the finite difference method of beam on elastic foundation.
