Structural Safety Risk Assessment Method of Long Distance Water Diversion Project Based on Multi-source Information Fusion

针对长距离引水工程结构安全风险评价过程中安全监测数据存在误差、人工检测信息复杂多样导致无法有效利用的问题,分别利用数据级融合与特征级融合分析方法对两类信息进行处理分析,并通过决策级融合分析方法与多层次模糊综合评价模型的使用,提出了基于多源信息融合的长距离引水工程结构安全风险评价方法。该方法构建了多源监测检测信息融合模型,得到了较为可靠、易于评价的数据源,提高了水工程结构安全风险评价结果的准确性。目前该评价方法已成功应用于某引水工程结构安全状态的评价中,并取得良好效果。

Aiming at the problems that the evaluation results are deviated from the reality due to the errors in the safety monitoring data and the complex varied artificial detection information in the process of structural safety risk evaluation of long distance water diversion project,the pixel-based fusion analysis and feature-based fusion analysis methods are respectively used to process and analyze the two kinds of information.By using the decision level fusion analysis method and the multi-level fuzzy comprehensive evaluation model,a method of structural safety risk evaluation of long-distance water diversion project is proposed based on multi-source information fusion.This method constructs a multi-source monitoring and detection information fusion model,obtains a relatively reliable and easy to evaluate data source,improves the accuracy of diversion engineering structure safety risk assessment results,and achieves good results.
