To accurately evaluate the comprehensive utility tunnel under river shield tunnel construction safety, reduce the safety accidents in the construction process, based on the method of risk breakdown structure (RBS), risk evaluation index system of four first-level indicators was constructed including engineering geological risk and comprehensive utility tunnel itself risk, environment risk, construction risk management. Based on the linear combination of interval number analytic hierarchy process (AHP) and indicator correlation method (CRITIC), the comprehensive weight was determined. Based on matter element theory, the weighted average relation degree was calculated to determine the final evaluation result. This method was applied to the comprehensive pipe corridor project of Yueyang Avenue sewage treatment at the Wangjia River section. Monte Carlo method was used to analyze the sensitivity of 15 basic indexes based on matter-element theory. The research results show that the construction project of Yueyang Avenue sewage treatment comprehensive pipe corridor at Wangjia River section is medium-risk, which is consistent with the actual situation. The sensitivity analysis shows that the surrounding rock strength and the buried depth of tunnel are more sensitive. The research results can provide a basis for the safety control decision and measure making of the project.
