摘要

摘要: 了解人工冻土的蠕变性质对安全建井是非常必要的。目前常用的人工冻土蠕变整数阶模型存在元件多的不足,通过将伯格斯模型串联黏壶替换为分数阶导数黏壶,建立分数阶导数伯格斯蠕变模型来模拟稳定蠕变阶段;在分数阶导数伯格斯模型中串联加速元件,建立分数阶导数加速伯格斯蠕变模型来模拟加速蠕变阶段。通过对比分析分数阶伯格斯蠕变模型计算结果与试验值,表明所建立的蠕变模型可较好地反映人工冻土的各阶段蠕变过程,可为人工冻土蠕变计算提供一种新方法。

Abstract: It is very important to master the influence of creep characteristics on artificial frozen soil to the engineering safety under construction of freezing method. For the creep,the integer order calculus constitutive relation of artificial frozen soil needs too many components and has other disadvantages,replaced the serial mode of Burgers model with fractional oder derivative function model,fractional order derivative Burgers creep model was constructed to simulate the steady stage of creep. Connected acceleration element in the fractional order derivative Burgers model,the fractional order derivative acceleration Burger creep model to simulate the acceleration stage of creep was constructed. By comparing the result of fractional order derivative Burgers creep model with trial value,the established creep model preferably reflected each stage of creep process of artificial frozen soil. Fractional order derivative Burgers model for artificial frozen soil was a new method for artificial frozen soil creep calculation.
