摘要
针对乌都河水电站二期工程岩溶地区水文、地质条件复杂,各种岩溶形态发育齐全,产汇流条件各不相同等问题,在规划设计阶段根据流域暴雨洪水特性,结合参证站历史洪水数据,对电站坝址及厂房洪水进行了定量计算.分析结果表明:工程区统计参数P=1%的洪峰模数为15~20 m^3/s·km^2,计算得P=1%的洪峰模数为15.5m^3/s·km^2,计算成果比较合理,符合库容小、河道型水库类型.
In the karst area of the 2nd phase project of Wuduhe Hydropower Plant, the hydrogeological condition is extremely complete due to the various karst forms and different runoff conditions. In order to accurately grasp the influential regularity of Karst landform on the flood and to ensure the river and dam＇ s running safety during flooding, according to the characteristics of the rainstorm and flood in the river basin, as well as the historical flood data of the station, the flood quantitatively calculation has been done during the planning and design stage. The analysis results show that, in the project area, the statistical flood peak modulus of P = 1% is 15 -20 m^3/s·km^2 and the calculation results of P = 1% is 15.5 m^3/s·km^2, the calcula- tion results are rational, in accordance with the reservoirs of small storage and river-type.
