ABSTRACT: The research of water conservancy project construction schedule risk analysis, risk factors, pre-human control of controllable factor and uncontrollable factors for the development of response measures, the probability of risk reduction, to plays a very important role in successful completion of water conservancy project. In this regard, according to the actual situation of water conservancy projects and combined with relevant literature, the paper establishes 7 first level indexes and 22 two level indexes that affect the construction schedule risk of water conservancy projects. Then, the triangular number Fuzzy-AHP model is constructed to calculate the weight of risk factors, and the fuzzy comprehensive evaluation method is used to evaluate the risk. In the Hui Xian section of the middle route of South to north water diversion culvert Yu He river protection wear reinforcement engineering for example, the higher the risk, the greater the weight factors, take preventive measures to reduce the risk, to control the total construction schedule risk, provides a reasonable way to control for the construction of water conservancy project schedule risk.
