本文的工作对水力旋流器的设计和选用有一定的参考价值。

The integrated risk between hydraulic, hydrologic uncertainty and the construction scheduling uncertainty should be analyzed. The paper puts forward the risk analysis model for the construction scheduling and the risk analysis model for construction diversion on the assumption that the construction scheduling is affirmable. Thus the Monte-Carlo method is used to simulate the integrated risk of construction diversion system considering hydraulic, hydrologic uncertainty and the construction scheduling uncertainty.

以风险分析为核心，将各种不确定性因素辐合起来研究施工导流系统的综合风险，提出施工进度计划风险分析模型和假定坝体施工进度确定条件下的施工导流风险分析模型，在此基础上，建立基于Monte-Carlo方法全面考虑水文水力不确定性以及施工进度不确定性的施工导流系统综合风险分析模型。
