内容記述 |
In this study, focusing on the quantitative evaluation of the mechanical behavior of kaolin clay at the micro scale, the deformation behavior and strength in the micro region were examined. Furthermore, the strength of the microscopic area obtained from the indent test was compared with the strength obtained from the unconfined compression test.
From the creep test results based on load control, it was found that the deformation characteristics differed at a certain water content in a microscopic region. It was also found that the liquid state of clay can be judged by this test. From the cycle indentation tests based on displacement control, it was found that the hardness differs in strength characteristics at a certain water content in a microscopic region. The displacement control test in the micro region showed that the liquid state of clay can be evaluated from the viewpoint of strength evaluation. As a result of examining the effect of the loading rate on the strength, the obtained strength was almost constant for the loading rate from 0.05 to 0.5 mm/s, and it is considered that there is no effect on strength due to loading rate. Compared with the undrained shear strength obtained by the unconfined compression test, the strength derived by micro-indenter was almost the same. In particular, it is considered possible to evaluate the strength in a microscopic region by using a rate in the range of 0.2 to 0.5 mm/s. |
