Risk Assessment of Beam-type Aqueduct Based on Game Theory-Cloud Model
As an important cross structure in large-scale water transportation project,the safety and stability of the beam-type aqueduct directly determine the normal operation of the main water transportation channel.Once it fails,it will cause serious disasters and socio-economic losses.In view of this problem,12 risk indicators of three major categories affecting the scouring failure of aqueduct piers,the instability of wrapped head slope,and the water retaining of aqueduct body were selected in this paper to establish a cloud model risk assessment model,using the analytic hierarchy process to determine the subjective weight,the entropy weight method to determine the objective weight,and the game theory weight method to determine the combination weight.Six typical beam aqueducts of a large water conveyance project were selected as the research objects for case studies.The results showed that this study provided a new approach for risk assessment of cross structure in large water conveyance project.
