Abstract:To adapt to the characteristics of uncertainty,randomness and dynamic feedback of risk factors,a new risk evaluation system for the water inrush of water-rich karst tunnel was established,and a fuzzy comprehensive evaluation method based on the cloud model was proposed.5 level-1 indicators and 29 level-2 indicators were selected to construct the evaluation indicator structure.The combination of hierarchical analysis,entropy weighting and weighted average calculation methods was used to reasonably allocate the weight of each indicator.The cloud generation algorithm was used to calculate the cloud digital characteristic parameters and generate a sufficient number of cloud droplets.This method was applied to the water inrush risk assessment of a tunnel in Guizhou Province.The results showed that most of the cloud droplets in the comprehensive cloud model were between“medium risk”and“high risk”,which was consistent with the results of actual excavation and geological radar analysis.The proposed fuzzy comprehensive evaluation method based on cloud model provides a good practical reference for the risk assessment of water inrush in the water-rich karst tunnel,and provides a reference for future tunnel quality control and life estimation.
Keywords:water-rich karst tunnel  water inrush risk  cloud model  evaluation indicator system  cloud digital characteristic
