摘要

在深入研究桩土相互作用机理及基桩极限承载力变步长灰色预测方法基础上，针对现有基桩极限承载力灰色预测模型之基桩Q-S曲线导数与背景值确定方法的局限性与不足，结合Q-S曲线发展规律，提出了基桩极限承载能力的改进变步长灰色预测模型与方法，并初步探讨了基桩极限承载力灰色预测方法的精度与可靠性。通过工程实例计算并与同类方法计算结果进行比较分析，表明了所建模型的合理性。

Abstract

Based on careful analysis of variable step size gray predicted method to determine ultimate bearing capacity of single pile and interaction between soil and pile

the problems of the present model to predict ultimate bearing capacity of single pile about derivative of single pile Q-S curve and method to determine background value are pointed out. According to the law of the development on single pile Q–S curve

an improved variable step size gray predicted model to determine ultimate bearing capacity of single pile is put forward. Finally

accuracy standard and reliability of gray predicted method to determine ultimate bearing capacity of single pile are tentatively studied. By computation of the engineering example and comparing with other methods

it is shown that the model proposed is reasonable.
