摘　　要：Rapids and shoals in the channel have a huge impact on the safety of the ship navigation, Based on the principle of a rubber dam can always adjust the height of the dam and raise upstream water level, This thesis creatively proposed the principle which applied to rapids and shoals in the Channel. In order to achieve the purpose of assisting ship through the channel safely. In this paper, through theoretical calculations verified the rubber dam has characteristics of raising water level, increasing the depth of the shoals, reducing the flow velocity, reducing water surface slope and improving the conditions of navigation. Therefore, this study has a wide range of practical value and application prospects in the project
