Quality and Safety Analysis of Composite Foundation Dam Based on Dam Safety Evaluation Model
The quality and safety of concrete dams are studied,and a generalized evaluation method of seepage flow is proposed.Considering the influence of water level and time on the seepage risk of foundation dam,a comprehensive safety evaluation method is proposed combining the engineering analogy method and Bayesian method to realize the evaluation of the seepage damage risk of composite foundation dam.In the prediction of seepage flow at different locations of composite foundation dams,the comprehensive method can accurately monitor the seepage flow of the dam body with an accuracy of 94.65%,while the accuracy of the traditional material coefficient method is only 64.56%.At the same time,the comprehensive method is close to the actual results in the monitoring of the annual seepage damage loss efficiency.The research result has important reference value for the quality supervision of water conservancy projects.
