西福河大桥对河道行洪影响分析

西福河是增城市第二大河流,为当地的主要行洪、排水、排涝通道。某高速公路西福河大桥跨越西福河并在河道行洪区域内布置路基、桥梁等构筑物。为了减小建桥后对两岸河堤、农田、村庄造成影响,应分析桥梁建设对河道行洪影响。本文根据西福河大桥设计成果、所跨越西福河河道情况进行阻水分析,并通过建立数学模型进行壅水计算,根据分析结果就本工程建设对河道泄洪的影响、对河势稳定的影响、进行评价,并对设计方案提出调整意见或建议。

Analysis of Xifu River Bridge on river flood impact

Xifu River is the second largest river in Zheng city,mainly channels for local flood, River Bridge crosses a highway Xifu River and arranged drainage.Xifu roadbed ,bridges and other structures in the river flood zone.In order to reduce the impact on cross-strait bridge embankments ,farmland, villages, should analyze the impact of bridge construction on river flood.Based on the design results Xifu River Bridge,the river channel carried across the water blocking situation analysis and mathematical models by backwater calculations, based on the analysis on the impact of the construction of river flood, the impact on the stability of river, and carried evaluation and design of proposed adjustments comments or suggestions.
