It is very difficult to reflect the thickness of revetment riprap if it is checked and accepted by the conventional inspection method in the quality inspection because of siltation and sedimentation in the riprap bank.In order to reflect the actual quality of the rubble,this paper researches the method of quality detection in the process of siltation and settlement of bank protection,and finds out that the thickness of the rock deposit is detected by real-time detection+sweep detection,and the coverage is detected by sidescan.
