Safety Evaluation of Gravity Dam Based on Improved Cloud Model
摘要
Abstract
To enhance the accuracy of gravity dam safety assessment,this paper proposes a gravity dam safety evaluation model based on an improved cloud model and applies it to Longgang Reservoir.The results show that the method can effectively address the shortcomings of traditional single-step reverse cloud models by using a multi-step reverse cloud transformation algorithm for extracting and processing cloud numerical features from random sample data and iteratively refining sample data to obtain improved cloud parameters.The constructed gravity dam safety evaluation model,integrating the game theory with a multi-step reverse cloud transformation algorithm,provides effective safety assessment based on monitoring data.The safety level calculated from the relative closeness between standardized monitoring data of Longgang Reservoir gravity dam and the normal cloud safety evaluation grade is"low risk",indicating that the dam is in a safe operating state,consistent with the actual situation.关键词
