农田混凝土衬砌渠道质量模糊综合评价

为有效反映农田混凝土渠道衬砌工程质量评价指标体系中主、客观评价信息，引入基于德尔菲法与层次分析法相结合的融合权重；运用模糊综合评价法建立了农田混凝土衬砌渠道质量模糊综合评价模型。通过工程实例验证，结果表明：该工程项目质量良好、合格和不合格的隶属度分别为39.9%、60.1%、0%;整个工程项目的质量最终评价为83.48，评定该项目的质量等级为合格。结合工程项目后期运行状况，并与传统评价结果对比，证明农田混凝土衬砌渠道质量模糊综合评价方法可行、有效。

Fuzzy comprehensive evaluation of concrete lining quality in field irrigation channels

Objective and impartial evaluation of concrete lining quality of irrigation canal in the farmland is of great significance to the quality of water-saving irrigation project. In order to effectively reflect the subjective and objective evaluation information of concrete channel project quality in evaluation index system in the farmland, this paper introduced the combing weighting of the Delphi method and analytic hierarchy process using Fuzzy mathematical evaluation. It established a fuzzy comprehensive evaluation model of farmland concrete channel engineering quality. Through the engineering verification, the results showed as follows: the distribution of good, qualified, and unqualified projects were 39.9%, 60.1%, and 0%, respectively; the final quality evaluation score of the whole project was 83.48 and it was concluded as qualified. Combined with the later operation status of the project and the traditional evaluation results, it proved that the fuzzy comprehensive evaluation method of farmland concrete channel is feasible and effective.
