Evaluation and application of mass fair-faced concrete decorative surface construction scheme based on combination weighting method
In the construction process,mass concrete is prone to varying degrees of pollution,uneven concrete surfaces,and inadequate aesthetic quality.When considering a combination of technical criteria such as economy,aesthetics,environmental friendliness,and technical feasibility,selecting the optimal decorative scheme has become a important consideration for ensuring construction quality.Therefore,this paper utilizes a combination weighting method based on the Analytic Hierarchy Process to calculate subjective weights and employs the rough entropy method to calculate objective weights.Furthermore,by calculating the error of weight preference coefficient,the combination weight is obtained,and an combined with cooperative game metod and minimum deviation as the objective,the combination weight is determined for evaluation.Taking the Jialing River Cascade Canalization Lize Navigation Hub Shiplock Project as an example,multiple schemes are compared,and selected from the processes of foundation treatment,material mix ratio optimization,and protective material coating.The model used calculated that the imitation clearwater concrete coating construction,with a weight value of 58.35%,is selected as the optimal scheme.After being put into practical use,the appearance quality of the ship lock concrete is significantly improved,in order to provide reference for other similar engineering projects.
