| Outline of Final Research Achievements |
In recent years, geosynthetic clay liners are used as impermeable materials in small earth dams because of lack of core materials. However, the design for small earth dams with GCLs has not been established yet. In the present study, consolidation tests, direct shear tests for soil/GCL interfaces and shaking model tests have been conducted in order to reveal fundamental behavior of GCLs and dynamic behavior of small earth dams with GCLs under conditions considering circumstances of small earth dams. As a result, it can be revealed that the water-barrier performance and the shear strength likely to be sufficient under small confining pressure condition such as small earth dams. On the other hand, the experimental results have revealed that GCLs could not be expected as reinforcement materials and the embankment’s failure mechanism depends on the setting shape of GCLs.
