(2008): A tilt table device for testing geosynthetic interfacees in centrifuge
GEOTEXT GEOMEMBRANES, 26, 31-38; ISSN 0266-1144 FullText FullText_BOKU

Abstract:
The 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 100 kPa. 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. (C) 2007 Elsevier Ltd. All rights reserved.
