| Abstract: |
| 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. |
