Abstract:

Shear strength is the principle engineering property which controls stability of soil mass under load. Its governs the bearing capacity of soil, stability of slopes in soils, the earth pressure against retaining structure and subgrade in highway. In soil structure interaction problems often becomes important to make a good estimation of friction of frictional resistance between ground and foundation. The information interface friction angle of soil against frictional surfaces is of great interest among research in soil structure interaction. Retaining wall is one of the important structure which are used mainly to retain soil mass hence need proper design. Present study includes series of DST to investigate the interface friction angle of different friction surfaces (jute, geotextile) with three soil samples (sand, murrum, clay). Using these friction values active earth pressure is evaluated by Rankine’s, coulomb’s method, and poncelet’s , culmann’s method.
