At present, the global tunnel construction industry is developing rapidly, but accidents are also common. A large number of casualties and property losses alarming people. It urgent to pay attention causes accidents, ensure safety sites, reduce accidents. Through literature case analysis, we have sorted out 35 typical causative factors for research which divided into 7 types. Based on variable system, prepared a measurement questionnaire, 536 valid questionnaires were collected. The structural equation model (SEM) was used study relationship between these variables. influence mechanism interaction variables analyzed in depth terms intensity path coefficient. results showed that following six latent significantly accidents: human factors, material geological exploration design, technical management, natural conditions. Natural conditions most significant impact, followed by management. Particular should be paid education, training, management risk control. helpful establish cause theory guide formulation policies projects, safety.
