Research On Application Effect Of Steel Box Girder Technology In Expressway Project

Green,efficient,safe,economic and rapid development concept is the main goal of expressway construction.This paper mainly makes a comprehensive evaluation of the application of steel box girder technology in the construction of expressway,aiming to explain the embodiment of steel box girder technology in the engineering quality,engineering progress,construction safety,cost control,environmental protection and other aspects in the application process of Zhounan expressway.In order to evaluate the application effect of steel box girder technology in expressway project objectively and accurately,AHP and entropy weight method are used to analyze the evaluation indexes from subjective and objective points of view,and the fuzzy mathematics theory is used for comprehensive evaluation.First,according to the manufacturing process of steel box girder,the evaluation index of its application effect in expressway project is constructed;then,the combined weight of each evaluation index is determined by AHP and entropy weight method,and the evaluation index is quantified and the corresponding evaluation grade standard is established,which is divided into four grades;finally,the evaluation model is constructed by combining the fuzzy membership function,and the steel is obtained by fuzzy comprehensive evaluation The application effect of box girder technology in expressway project.The rationality and practicability of the method are proved by the analysis of a practical project.
