摘要

根据《港口工程桩基规范局部修订》关于m法的新解释，结合某码头2根大直径钢管嵌岩桩的试桩资料总结了m值与泥面处位移的指数关系以及m值对桩受力特性的影响，发现规范建议的m值难以适应大位移情况下的取值要求。建议通过收集大量有关大位移情况下的试桩资料，根据m值和泥面处位移的指数关系，统计分析出在各种土质条件下相应于某一大位移时m值的取值范围，为工程设计提供依据。

Abstract

According to new explanation about the m-method in Code for Pile Foundation of Harbour Engineering Supplement and the test pile data of two large diameter rock-socketed steel pipe piles in a wharf

the power function relationship between the constant m value and pile head deflection is concluded; and even the behavior of pile reaction under the influence of m value is obtained too. These can reach a conclusion that the m values suggested in the code can not be used in the case of large deflection. Therefore

by collecting lots of test pile data

it is necessary to establish the corresponding relationship between the m value and large deflection under different soil conditions based on that relationship described in this paper. These results can help to provide reference for lateral loaded pile design.
