| Outline of Final Research Achievements |
Model tests for internal erosion of geomaterial have been conducted to clarify the mechanism of the occurrence of internal erosion and the progressive failure. A constitutive model for the internal erosion, that is, the erosion criteria and the erosion rate were proposed based on the tests.
Then, the numerical method was proposed to predict the internal erosion process, in which the constitutive model of erosion was introduced. The dissociation and erosion coupled method was proposed. The erosion process and the gas hydrated production process were reproduced using the proposed numerical method.
