With the rapid development of the Yangtze River waterway construction,maintaining and managing the existing waterway regulation buildings has become an important task.Beach protection structures along the Yangtze River,despite their commonality,lack comprehensive research on their operational status in China.This study a-dopts an extension cloud theory that incorporates indicator fuzziness to establish an evaluation model for beach pro-tection service status.Drawing from monitoring data,decades of maintenance experience and relevant specifica-tions,we developed an evaluation index system.Utilizing a combined approach of order relationship and entropy weighting,we comprehensively determined index weights.Through model calculations,the service status level of beach protection can be accurately assessed.Application of the model to evaluate the service status of beach protec-tion at Xinjiu Waterway in the midstream of the Yangtze River yielded consistent results with actual engineering conditions.Verification confirms the model's accuracy in correctly identifying beach protection service status,guid-ing daily maintenance and promoting intelligent maintenance practices along the Yangtze River waterway.
