A tilt table device for testing geosynthetic interfaces in centrifuge
AbstractThe shear strength of geosynthetic interface can be determined by either tilt table tests under low pressure or direct shear tests under high pressure. In the present paper, a tilt table device for testing the interface shear strength in geotechnical centrifuge is presented for the first time. By combining the advantages of tilt table and centrifuge, our tests cover a wide range of pressure from 10 to 100kPa. After a detailed description of the tilt table device, the test process and evaluation procedure are presented. The softening behaviour in the post peak regime is investigated by controlling the displacement with a relaxation mechanism. The test results in centrifuge are discussed and compared with tilt table tests and large direct shear tests in 1-g environment.
