Three Gorges Project has huge comprehensive utilization benefit,and many engineering construction features,such as large investment cost, long construction time,complicated engineering system, many factors of uncertainty,and great influence upon society.Thus, the investment risk has become an issue for which investors are extremely concerned. This risk can be quantitatively analysed, using the computation model which is developed by combining the graphic estimation and review technique (GERT) with Monte Garlo random simulation including correlation factor handling function.GERT random network is worked out by directly referring to relevant construction network charts,so as to bring the investment resolution,risk factor identification,and risk quantification to be more visualized,as well as the analysing process more approaching the actual one. This investment risk analysis model is adaptable for water conservancy and hydropwoer engineering system.
