EFFECTS OF LEACHING ON EARTHQUAKE - INDUCED RESIDUAL DEFORMATION OF ARIAKE CLAY DEPOSITS
|

| 抄録（英）： |
It is widely known that the sensitivity ratio of Ariake marine clay increases with leaching. Therefore, it is supposed that the mechanical properties of such clay considerably change and the shear strength decreases, if it is subjected to cyclic load as a disturbance force, like earthquakes. In the present study, static shear tests after subjecting to cyclic load were performed on Ariake clay with the leaching. The stability of earth structure on Ariake clay deposits with leaching during earthquakes was investigated. Undisturbed samples of the clay sedimented in the sea area were used in all the tests. Furthermore, a residual deformation analysis was also conducted on the basis of the test results described above. Consequently, the effect of leaching on the behavior of Ariake clay deposits was considerable during earthquakes.
