摘要
溃坝峰顶流量的计算是溃坝风险分析的基本内容,不同的经验公式涉及不同参数适合于不同的溃决方式。本文以东大滩水库为研究对象,通过调洪演算分析该水库具有遭受超标洪水溃坝的危险,在此基础上,选定四种不同溃口流量的经验公式进行计算,选择出适合于该水库溃口流量的计算公式。
Calculation of dam-break peak flow is the basic content of the risk analysis of dam.Different empirical formula include different parameters.Taking Dongdatan Reservoir as object,this paper predicts the dam-breaking risk suffering from exceeded flood by regulating calculation analysis.on this basis,four different empirical formula were selected for flow calculation and a suitable equation for the flow in the reservoir is proposed.
