Abstract: Based oa the analysis of basic characteristics of the Luzhou reach in the Changjiang River，Combine the implementing scheme of the second stage of the project of container dock put forward in model test of the bed definitely，adopted the two-dimentional rivers mathematics model of level and carried on the water—line and flows in field to analyse that is calculated，study the change open up to navigation the condition after the second stage of the project is built，result indicate build quay section this open up to navigation terms can satisfied with the request of opening up to basically．

Key words: water current, waterway, analysis, 2-D mathematical model
