Scientifically understanding the multidimensional vulnerability of UORA is a prerequisite for implementing stock renewal. However, existing vulnerability assessment methods for UORA suffer from limitations such as subjective weight assignment, and insufficient handling of uncertain information, leading to inadequate support for precise renewal decisions. To address these gaps, this study proposes a novel multidimensional vulnerability evaluation framework. A vulnerability evaluation index system is constructed from physical space, infrastructure, functional adaptation, ecological environment, and social governance. A comprehensive evaluation model is established by integrating the combined entropy weight method and the unascertained measure theory. This methodological innovation enhances the objectivity of weight determination while effectively addressing unstructured data and uncertain factors in vulnerability assessment. The empirical results show that the vulnerability evaluation results of the six projects are clearly polarised. High-risk clusters need to prioritise the initiation of engineering interventions and social governance reconstruction; for medium-risk projects, dynamic monitoring and adaptive management should be strengthened. This study provides a priority standard and scientific support for renewal decisions and promotes the transformation of vulnerability assessment from a single diagnosis to a systematic governance paradigm..</div></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"17 2","pages":"Article 104003"},"PeriodicalIF":5.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146023814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using data from 44 prefecture-level administrative regions along the Yellow River mainstem from 2014 to 2023, this study systematically revealed the spatiotemporal evolution of coupling coordination within the WC-WR-SED system and its influencing factors through the integrated application of the coupling coordination degree model, spatio-temporal geographical weighted regression (GTWR), and the Geo-detector method. The results indicated that the coupling coordination degree exhibited a stable gradient pattern, with “downstream > midstream > upstream”, and the overall differences evolve in an “inverted U-shape” pattern, with intra-provincial differences being the primary contributor. The influence of factors such as the proportion of unconventional water utilization to total water use and Engel’s coefficient showed significant spatial heterogeneity, accompanied by nonlinear enhancement effects among these factors.

This study investigates the local scour characteristics of bridge piers in the transition section of the Qiantang River, utilizing multi-beam echo sounding (MBES, vertical accuracy:±0.02 m) and high-resolution underwater 3D imaging sonar for data acquisition. The results reveal that the maximum local scour depth reaches 9.3 m, with the scour hole exhibiting an elliptical shape. When pier dimensions are similar, the scour hole width shows a strong correlation with the maximum scour depth, approximately four times the width of the pier cap. In contrast, the scour hole extension along the flow direction exhibits no significant correlation with scour depth but correlates with the pier cap length, approximately twice its dimension. Based on the measured data, the safety of bridge piers in the transition section was evaluated. It was found that the piers PM5-PM6 and PM8-PM10 of Bridge II, as well as the main piers of Bridge III, experienced significant scour depths, posing potential structural risks. The study recommends implementing protective measures for severely scoured piers and establishing long-term monitoring to ensure structural stability.

The Transformer architecture effectively learns long-range temporal dependencies in sensor data, while MC Dropout approximates epistemic uncertainty arising from model limitations. CP complements this by producing prediction intervals that capture aleatoric variability caused by noise and operating conditions. The framework is validated using NASA’s C-MAPSS FD001 and FD003 datasets.
