承德旺财铁选厂河道堤坝防洪能力分析

Analysis of Riverbank Flood Control Ability in Chengde Wangcai Iron Ore Processing Plant

为了确保旺财铁选厂的正常运行和岸边村庄的生命财产安全,掌握旺财铁选厂防洪堤坝防洪能力,通过收集大量水文和降水资料,并采用多种途径分析河道设计洪水及行洪水位。结果表明,防洪坝下断面行洪能力略低于5年一遇防洪标准,厂区下游的防洪坝需加高1.2m以上。通过上述措施方能保障旺财铁选厂的防洪安全。

To ensure the normal operation of Wangcai Iron ore processing plant and safety of people＇s lives or property near the riverbank, to master flood control ability of Wangcai Iron ore processing plant, more methods were used to analyse design flood and flood control level of the river by collecting a lot of hydrological and rainfall data. The results show that the flood control standard of the lower profile was slightly below the five year frequency, the flood control dam of the lower reach needed to heighten above 1.2 meter. The above measures were the guarantee to the flood control safety of Wangcai Iron ore processing plant.
