| 摘 要： | 从桩基计算应用的角度,针对m法的适用条件、m的取值、桩位和非均匀土体对m法的影响等方面进行分析,表明m法在实际应用中存在较大误差,其计算成果应慎重采用,并设法验证。应用计算机技术和非线性有限元法,可较好地反映桩的承载机理,为设计提供可靠依据。

| Abstract: | From the angle of application of M-method in computation of pile foundation,the analyses on applicability and obtaining of m value and affection from plie displacement and nonuniform soil are given.It is shown that a big error existing in the actual application of M-method.So,the calculated result should be used carefully and be substantiated before being used.The theory of pile bearing load can be explained well by computation technology and non-linear finite element,which can provide a reliable warrant fo... |
