abstract="In order to scientifically design bridge span scheme for changeable riverbed, case analysis and historical analysis methods were employed to study the problem of Jingzhou Yangtze river bridge area where navigation safety was impacted by riverbed evolution. It was pointed out that the most significant risk for bridges in changeable riverbeds was that channel displacement caused by riverbed evolution made ship navigation move from navigable bridge opening to non-navigable one, and it was suggested that navigable bridge opening should cover thalweg and swing range of deep channel which may form new navigation channel. Then, riverbed evolution mechanism of Libu bridge area which was planned to be built was studied according to proposed principles, swing range of 3.5 m deep channel and thalweg under the lowest navigable stage was chosen for bridge span layout. Finally, 1120 m scheme was confirmed to be able to guarantee navigation safety of Libu Yangtze river bridge under influence of riverbed. © 2021 China Safety Science Journal<p /><p>Language: zh</p>",
