Comprehensive evaluation of construction safety of diversion tunnel based on improved catastrophe series method
To ensure the construction safety of the diversion tunnel,an improved catastrophe series method for the construction safety evaluation model of the diversion tunnel is constructed.Firstly,the safety mutation character-istics of the diversion tunnel construction are analyzed,and the construction safety evaluation index system of the diversion tunnel is constructed.Then,the qualitative and quantitative evaluation indicators are obtained by using the ISM-ANP combined weighting method to improve the reliability of the evaluation data.Based on the weighted results and the catastrophe series theory,an improved catastrophe series comprehensive evaluation model was constructed.Finally,taking a water diversion tunnel project as the evaluation object,the model is used to evaluate and analyze the construction safety status of the water diversion tunnel.The results show that the construction safety evaluation level of a diversion tunnel project is general,and there are certain safety hazards during the construction of the diversion tunnel.The improved catastrophe series safety evaluation method proposed in this paper has high accu-racy and provides a theoretical reference for the safety evaluation of diversion tunnels.
