In order to know the friction between immersed reinforced concrete tube elements and foundation bed in different working conditions, we carried the experimental studies on the friction coefficient between the immersed tube element model and the rubble foundation bed, and the settlement of the rubble foundation bed in different conditions, such as the conditions with different rubble size, with the fully paved and furrow-paved rubble foundation beds, and in different negatively buoyant conditions. We analyzed the test results, which can provide references for the force calculation of immersed tube installation.
