Shandong Water Polytechnic, Rizhao, 276826）Abstract: Through the separate analysis of channel diversion 、 tunnel diversion and dam gap discharge, this paper establishes the computational model for joint discharge during construction by applying the hydraulic computation theory. On the joint discharge basis of construction diversion system, using the Monte-carlo method to simulate the flood and discharge process, the risk model analyses the distribution of the flood level in front of the cofferdam and dynamic risk under different diversion standard by flood routing model and the cluster analysis model. The case study institutes that the computational model for joint discharge and risk analysis model of construction diversion schemes are reasonable and effective.Key words: construction diversion; joint discharge; risk analysis; Monte-Carlo method; cluster analysis1. 引言施工导流工程是风险工程，在进行导流方案确定、导流方式选择、设计优化时，工程的风险应作为一个指标参加决策，所以如何确定施工导流工程的综合风险就显得十分重要。目前，施工导流工程中所存在的风险问题己经引起广泛的重视，并将风险与导流标淮[1]的选择联系起来进行讨论。而进行...
