Abstract

As an important component of water conservancy infrastructure, canals help improve the uneven distribution of regional water resources. However, in their construction and operation processes, which are affected by a variety of complex factors, canal linings often produce various problems that greatly reduce their overall quality and lead to water resources being wasted. To evaluate and determine the factors and key procedures affecting the construction of concrete canal linings so as to improve their quality, an evaluation mechanism based on statistical analysis, the fuzzy attribute hierarchical model (FAHM), and the cloud model is proposed in this paper. Using this method, we first determine the problems affecting the construction quality of canal linings through statistical analysis, through establishing a questionnaire based on these factors; then, we use FAHM to identify the main quality problem factors; finally, we use the cloud model to analyze the overall construction quality of concrete canal linings. The quality evaluation and key construction procedures are determined, and a case study is conducted taking a canal lining project in China as an example, for which the final evaluation result is grade II. At the same time, a comparative study is carried out using the AHP and cloud models. The results indicate that the proposed method is more reasonable and feasible than existing methods, thus laying a foundation for the follow-up quality control of canals.

摘要：渠道是水利基础设施的重要组成部分，对于改善区域水资源分布不均具有重要意义。然而，在建设与运行过程中，受多种复杂因素影响，渠道衬砌常出现各类病害，严重降低整体质量，造成水资源浪费。为识别并确定影响混凝土渠道衬砌施工质量的关键因素与核心工序，从而提升施工质量，本文提出一种融合统计分析、模糊属性层次模型（FAHM）与云模型的综合评价方法。该方法首先通过统计分析梳理渠道衬砌施工质量常见问题，并据此设计调查问卷；随后利用FAHM识别主要质量影响因素；最后借助云模型对混凝土渠道衬砌的整体施工质量进行综合评价。据此确定质量等级及关键施工环节，并以国内某渠道衬砌工程为实例开展案例研究，得出最终评价等级为Ⅱ级。同时，本文将所提方法与AHP-云模型组合方法进行对比，结果表明，本文方法更具合理性与可行性，可为后续渠道质量控制提供科学依据。
