中文摘要：
桥梁桩基础计算中采用的m法只适用于桩顶位移较小的情况;而在地震、波浪等动力荷载作用下,桩侧土体已进入非线性,桩顶位移较大,因而m法的适用性值得探讨。将p-y曲线法用于桥梁桩基础计算的结果,与试验结果比较证明该方法的合理性,与m法对比分析以指出m法存在的不足。
英文摘要：
M-method adopted in the calculation of bridge pile foundationy only suitable to the case of small-displacement of pile head.However,displacement of pile head becomes lager becauses of the occurrence of soil nonlinearity when subjected to lateral dynamic loads,such as earthquake,wave,etc.As a result,the applicability of M-method should be discussed.The p-y method employed in this article was applied to the calculation of bridge pile foundations.Validity and reliability of p-y method were evaluated by comparing with field tests,and the disadvantages of M-method were pointed out afterwards.
