Abstract: To strengthen the safety management for hydroproject construction and to prevent and control accidents, the construction safety risk was analyzed by using structural equation modeling. A theoretical model which contains 4 latent variables and 12 observed variables concerning the construction safety was established based on structural equation. The coefficients were calculated by using AMOS 17.0. Twelve path coefficients and six correlation coefficients were obtained. The path coefficients respectively between company influence and company organization, construction site and technical measures, personnel quality and personnel training, as well as safety management and safety supervision were 3.03, 1.36, 1.36, 1.00, indicating strong connection between the factors. Measures inclusive of improving company influence, company organization, supervision mechanism, strict safety training and education were proposed. This research could be a reference for the reasonable safety assessment system in engineering construction.
