以某桥梁为例,对其设计流量、设计水位、壅水高度和冲刷深度进行了计算.计算结果显示,该桥梁的设计流量、设计水位、最大壅水高度、壅水影响距离和总冲刷深度分别为680 m3/s,34.3 m,1.4 m,151 m和2.35 m,均满足发生洪水时的防洪标准.上述结果表明,桥梁对河道的行洪走势和河势的稳定性影响较小.
Study on Flood Control Impact Assessment of Highway Cross River Bridge Engineering
A study was conducted using a certain bridge as an example to calculate its design flow rate,design water level,backwater height,and scouring depth.The calculation results show that the design flow,design water level,maximum damming height,damming influence distance,and total scouring depth of the bridge are 680 m3/s,34.3 m,1.4 m,151 m,and 2.35 m,respectively,which meet the flood control standards in case of floods.The above results indicate that bridges have a rela-tively small impact on the flood discharge trend and stability of the river regime.
