摘要

以Bothkennar和Pisa粘土率无关结构性特征试验为基础

对2类基于实测数据的典型解构函数特点进行分析比较

完善了参数评价及取值方法;进一步结合天然Batiscan粘土的CRS以及固结蠕变等率相关结构性特征试验结果

在解构函数中引入了率敏性影响

并利用CRS试验数据对率相关性解构函数的合理性进行了验证。结果表明

2类解构函数都能较好地反映率无关与率相关屈服解构过程

预测结果与试验数据吻合良好。

Abstract

Based on the strain rate-independent tests for structural characteristics of Bothkennar and Pisa clay

the characteristics of two types of typical deconstruction functions based on measured data were analyzed and compared

which improves the method of parameters evaluation and choice of value.Further

combining the results of the strain rate-dependent tests with structural characteristics on natural Batiscan clay such as CRS and consolidation creep tests

the rate sensitive influence was introduced into the deconstruction functions.Finally

the reasonableness of the strain rate-dependent deconstruction functions was verified by use of CRS test date.The results show that the two types of deconstruction functions can preferably reflect strain rate-independent or strain rate-dependent yield deconstruction process

and the predicted results are in good agreement with the experimental data.
