摘要

按遗传流变理论来推导软黏土的蠕变模型，提出了一种新的蠕变核函数形式的选取方法，即用修正Burgers模型的导数形式作为蠕变核函数，随着参数取值的不同，该经验模型能模拟蠕变发展到不同阶段的蠕变曲线，探讨了该模型能精确描述软黏土的蠕变变形的原因，模型具有参数少、物理意义明确，适用性强的特点，能有效地描述湛江软黏土的蠕变特性。该研究内容也是对分数阶微积分进行应用研究的一种新的尝试。

Abstract

A description of creep model of soft clay derived from genetic rheological theory

a new type of kernel function which is derivative form of Burgers model is put forward; the empirical model can simulate different creep stages with different parameter values. The model well describes different creep curves of soft soil; and the cause of which is probed. The proposed model has few parameters

which stand for specific physical significances; and it can be applied to simulate all kinds of soft clays

and can simulate perfectly soft clay from Zhanjiang area. At the same time

the research is also a new application of fractional calculus
