根据宗渠沟泥石流和堰塞体发育特征，在对可能溃坝型式、漫溢溃决临界水头、临界条件溃决流速和溃决临界洪峰流量进行分析计算的基础上，预测了不同暴雨频率下发生溃决的可能性；并依据溃坝流量计算结果对洪水和泥石流规模的放大效应进行了评价。这种预测方法对于堰塞坝的安全评价和防灾预警工作具有重要的指导意义。
根據宗渠溝泥石流和堰塞體髮育特徵，在對可能潰壩型式、漫溢潰決臨界水頭、臨界條件潰決流速和潰決臨界洪峰流量進行分析計算的基礎上，預測瞭不同暴雨頻率下髮生潰決的可能性；併依據潰壩流量計算結果對洪水和泥石流規模的放大效應進行瞭評價。這種預測方法對于堰塞壩的安全評價和防災預警工作具有重要的指導意義。

According to the development characteristics of debris flow and landslide dam in Zongqu Gully, based on the analysis and calculation of dam break type, critical head, flow rate and peak flow leaded to overflow burst, the possibilities of burst in different rainfall frequencies are forecasted, and the assessment for the amplifica-tion effect of flood and debris flow scale is obtained on the basis on the calculation results of dam break discharge. The prediction method has an important guiding significance for the safety evaluation and disaster warning of land-slide dams.
