Abstract：Because of Chongqing Road located in Qingdao being widen and adding a new skew bridge in its downstream,this leaded to wetted areas reduction and backwater superposition before the bridge.Due to the complexity of the calculation relationship with the backwater before the skew bridge,there was no simple calculation relationship in the existing specifications.In order to analyze the influence of flood discharge in the new skew bridge of the Baisha River,this paper established the two-dimensional flow model,and applied the model to calculate the change of the water level and velocity in the location of the project after the bridge rebuilding for the 50-year return period flood.Finally,this paper evaluated the influence of the Baisha River triggered by the new bridge.
