摘要: 传统的水电厂、变电站设计洪水计算方法都是以经验公式或推理公式为基础建立的简单计算法,计算结果的正确率都较低。采用MIKE SHE分布式水文模型,结合GIS与RS技术,对贵州喀斯特地貌区的六硐河甲茶水电站进行了洪峰流量计算,并与其他模型方法的计算结果进行了比较。结果表明,在洪峰计算中,MIKE SHE模型具有模拟结果更加精确、详细等独特优势,且适用于喀斯特地貌区。该模型的成功使用为今后类似地区的洪峰计算奠定了坚实的基础。

Abstract:

The traditional design flood calculation methods for hydropower plant are characterized as simple calculation methods established by empirical formula or reasoning formula and the correction rate of the calculation method is low. In the combination of GIS and RS technology, the design flood of Jiacha Hydropower Station on Liudong River in the karst area of Guizhou Province is calculated by MIKE SHE model and the calculation result is compared with that calculated by other models. It shows that the result of MIKE SHE model is more accurate and detail, which is suitable to the karst area. The successful application of the model laid solid foundation for future flood peak calculation in the similar karst area.
