该文基于内蕴时间理论对特定类型土质网纹红土的蠕变进行研究。作者先提出了单向固结条件下基于内蕴时间理论的土流变的本构方程,再通过对网纹红土未扰动土样进行了在分级连续加载与分别独立加载条件下的有侧限固结蠕变试验,然后将反算得出的蠕变曲线和相同条件下的试验得到的新的蠕变曲线进行比较,验证了本构方程的正确性。结果表明,作者所提出的土流变本构方程无论是分级连续加载还是分别独立加载都能准确地反映网纹红土的流变特性,这就更方便于实际工程的应用。
This paper studies the creep of a certain type of earthen textured laterite based on the intrinsic time theory. The author first proposed the constitutive equation of soil rheology under unidirectional consolidation and based on the intrinsic time theory. Then, by using the undisturbed soil samples of reticulate red clay under the condition of continuous loading and independent loading respectively, Consolidation creep test, and then compare the calculated creep curve with the new creep curve obtained under the same test conditions to verify the correctness of the constitutive equation. The results show that the rheological constitutive equations proposed by the authors can accurately reflect the rheological characteristics of reticulate red clay whether it is graded continuous loading or separately loaded, which is more convenient for the practical engineering application.
