| 内容記述 | This paper describes the results of a series of creep test by uniaxial compression on frozen silty clay at -7.5 and -15.0°C. From the analysis of the results based on the rate process theory, it was seen that both the free energy of activation and the volume of flow unit were raised with increasing temperature and applied force. This tendency is quite similar to that of polycrystalline ice published by Dillon and Andersland (1967), while it seems to be contrary to the results of un frozen clay analysed by Andersland and Douglas (1970). One possible way to understand reasonably all these results seems to be given by the concept that the stress is relaxed in unfrozen clay and is elevated in polycrystalline ice and frozen clay with the rise of applied stress. On the standpoint of this concept, it may be difficult for us to accept that such a mechanism of direct contact between clay particles as demonstrated by Andersland and Douglas takes place in the creep of frozen clay. Gradual increase of activation free energy with time under fixed temperature and stress may suggest that adsorbed water existing between particles and pore ice brings its effect on the creep process of frozen clay. Inferring from the quite similar tendencies between the polycrystalline ice and frozen clay, it would be concluded that the creep process of frozen clay was mainly controlled by the behavior of pore ice in it. Our value of flow volume ranging from 3.7xl03 to 3.2xl04 cubic angstroms is, however, too small compared to that of polycrystalline ice ranging from 2.5xl07 to 5.3xlO7 cubic angstroms. It may be explained by the fact that the icemade upin tortuous pore space of clay forms the interlocking structure with the clay particle. | |||||||
