渭河特大桥对两岸堤防影响分析

Great Bridge of Wei River impact analysis on both banks' embankment

在交通线路中桥梁是跨越河流的建筑物,位于河道中,桥墩缩窄了河道行洪断面,势必对河堤安全、河势稳定、输水安全及河道治理等产生一定的影响。根据陕西省临潼水文站和华县水文站的水文资料,对渭河特大桥桥位处的设计洪水位和壅水进行计算分析可知,在渭河大桥建成后对两岸堤防造成影响,对此进行分析评价,建议采取相应的补救措施。

The bridge is a building across a river in the traffic line located in the river,the bridge pier constricts flood cross-sections of a river channel,it is bound to engender a certain impact on the safety of embankment and water transmitting,stability of river regime and river training.According to hydrological data of Huaxian County and Lintong Hydrological Station in Shaanxi Province in this paper,an analysis is made of designing flood level and water of bridges located in the Weihe River,it is known that cross-strait embankment engenders a certain impact after the completion of the Weihe Bridge.It is suggested that corresponding compensating measures be made after an analysis of this.
