多桥并存背景下辽河特大桥的防洪影响评价研究

Study on the flood control evaluation of Liao River Grand Bridge under the condition of existing with other bridges

以京沈客运专线辽河特大桥为例,基于HydroInfo二维水力模型,对多桥并存背景下辽河特大桥的防洪影响评价进行了深入研究。模拟结果显示,大桥的建设对桥址上下游河道及两岸均影响较小,不需要采取额外的防护与补救措施。

Taking Beijing-Shenyang passenger special line, Liao River Grand Bridge as an example, this paper makes an in-depth study on the flood control evaluation of Liao River Grand Bridge under the condition of existing bridges with the 2-D hydraulic model based on Hydrolnfo, The simulation results show the bridge has so little influence on the upstream and downstream that no additional measures should be take.
