Shear strength and soil-steel interface friction of carbonate silt deposited in coral reefs were examined by direct shear box tests. A series of direct shear tests was carried out under both constant pressure and constant volume loading conditon in order to understand the shear behavior of silt and steel-silt interfaces. The steel silt interface shear behavior was found to be similar to the siltsilt shear behavior. The internal friction angle and the interface friction angle for carbonate silt obtained by constant volume loading tests were consistent with those obtained by constant pressure loading tests. Based on the steel-silt interface test, it was discussed that the skin friction capacity was depend on the normal stress level on the surface of pile developed under the constant volume condition.
