摘要 美国石油协会(API)新旧规范采用的砂土p-y曲线法是目前应用最广泛的两种砂土p-y曲线法,目前我国《港口工程桩基规范》(JTJ 254―98)直接采用了API新规范p-y曲线法。对API新旧规范采用的砂土两种p-y曲线方法进行了理论对比分析,并结合一个有较好量测资料的工程试桩试验,采用弹性地基梁的有限差分法,对上述两种方法与工程实例进行对比分析。 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.
