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。
Based on the structural characteristics of Bothkennar and Pisa clay unrelated to the structural characteristics of the test, based on the two typical measured data based on the characteristics of the typical destructor analysis and comparison, improve the parameter evaluation and valuation methods; further combination of natural Batiscan clay CRS and consolidation creep Rate-related structural characteristic test results, the rate-sensitive effect is introduced into the destructuring function, and the rationality of the rate-dependent destructuring function is verified by using the CRS test data. The results show that both of the two kinds of deconstruction functions can reflect the rate-independent yield-dependent deconstruction process well, and the predicted results are in good agreement with the experimental data.
