摘    要:基于唐家山堰塞坝溃决的实测数据,使用BREACH模型及中国水科院DB-IWHR模型,对唐家山堰塞坝溃决过程进行了反演分析,并对两种模型进行参数敏感性分析。研究结果表明:使用针对唐家山的参数,两种模型均可较好地反演唐家山溃决洪水的过程,BREACH模型的下游坡比和孔隙率是对结果影响比较敏感的输入参数;DB-IWHR模型在冲刷参数和下游水深计算两方面做了改善,较好地解决了这一问题;DB-IWHR提供了一个Excel格式的计算软件,数值分析稳定性好,使用简洁客观,可供类似堰塞湖应急处置时参考。

关 键 词:堰塞湖;BREACH模型;DB-IWHR模型;溃坝洪水分析;唐家山

Abstract:Based on measured data of the dam breach of Tangjiashan Barrier Lake, the process of the dam breach was analyzed using the BREACH model and the DB-IWHR model developed by the China Institute of Water Resources and Hydropower Research. A sensitivity analysis of the two models to different parameters was also performed. Results show that, using the parameters of the dam, the two models can both reflect the flooding process induced by the dam breach; the calculated results of the peak flow are more sensitive to the input parameters of the downstream slope and porosity in the BREACH model; the DB-IWHR model improves the calculation of the erosion parameter and downstream water depth, resulting in calculated results less sensitive to the input parameters; and the DB-IWHR model provides software in the Excel format, with a high stability in numerical analysis, which is transparent, self-explanatory, and friendly to practitioners.
Keywords:barrier lake   BREACH model   DB-IWHR model   dam breach-induced flood analysis   Tangjiashan
