潜山县兜儿寺大桥防洪影响评价分析

Analiysis of flood control evaluation of Douersi Bridge Project in Qianshan county

收集潜山兜儿寺大桥工程河段附近水文资料,运用相应规范提供的理论公式进行兜儿寺大桥防洪影响研究和评价,为大桥建设项目的开展提供防洪影响评价方面的技术支撑,为类似项目防洪评价编制提供参考.计算结果显示,该大桥对所处河段河道的流势、过流断面、防洪安全影响较小.

A large number of hydrological data of Douershi Bridge in Qianshan county are collected,and the flood control effect of Douershi Bridge is studied and evaluated by using the theoretical formula provided by the corresponding specifications.The calculation results show that the bridge has little impact on the flow potential,cross section and flood control safety of the river channel in which it is located,and provides technical support for flood control impact assessment for the development of bridge construction projects.
