摘要
本文在分析洪水风险率Poisson模型的不足后提出了洪水风险率分析的更新过程模型,并结合长江宜昌站的流量洪峰资料,探讨了这类模型的适用性。结果表明,该模型是洪水风险率分析的切实可用的模型。
The renewal process model of flood risk analysis has been presented after the shortcoming of the flood risk poisson model was analyzed and combined with the flood peak data at Yichang. The result shows that the renewal process model is a kind of suitable one for flood risk analysis.
