    New results of the slid characteristics of a typical earthquake landslide model based on shake table tests

    • In order to examine the slid characteristics of the typical landslide model triggered by strong earthquakes, physical models for shake tables are created and a series of tests are conducted by inputting sine seismic waves with different frequencies, duration and peaks. The following five interesting findings are obtained from the tests. (1) The slid-body may slide not only downward but also upward along the slid-belt when undergoes a strong shake wave and two yield accelerations (the downward and upward yielding acceleration) exist. (2) The data for slid analysis should be the local acceleration close to the slid-belt other than the acceleration at the bottom of the landslides model. (3) With time growing, the overall displacement of the slid-body along the slid-belt accumulates with the characteristics of the stepped wave in shake-table testes. (4) The slid characteristics of different wave periods are independent of each other and are nearly the same. (5) The slid characteristics of the slid-body are controlled by the downward and upward yielding accelerations and the vector sum of the downward and upward slide displacement along the slid-belt make up the overall permanent displacement in every wave period.
