Abstract

Abstract: The direct shear testing between the soil and contact structure interface is one of the efficient way of characterizing the contact properties of various materials. The interface testing device was modified from the conventional large scale direct shear testing equipment by separately preparing the concrete blocks at the bottom and the face blocks made with other soil material sample at the top. The interface direct shear tests were performed with various gravelly soils in Three Gorges area under different normal pressures and different moisture contents. The test results are satisfactory.

Key words: Gravelly Soils, Contact Interface, Direct Shear Tests, Moisture Contents
