| Research Abstract |
On this study, two testing equipment for evaluating the criterion of the seepage failures were developed. One is for the evaluated by the velocity of seepage flow, and the other by the hydraulic gradient. And the testing methods using them were proposed.Then the relation of these evaluation criteria was related with the physical property of soil, and those applicable conditions made clarified. Moreover, as the application about the criterion based on the velocity of flow, some model tests for stability of anatural dam against the toppling flow was carried out, and its problems and applicability were clarified.
