Construction Of 3D Model Of Expressway Engineering Quality Management

At present,the mileage of expressways in China has increased year by year.The expressway plays an increasingly important role in the transportation field,and it is increasingly important to the national economy.Objectively,this also puts higher requirements on the quality management of expressway engineering.First of all,the concept of highway engineering quality is analyzed.Secondly,it introduces the theory related to this research in a general way.Finally,it summarizes the related literatures at home and abroad,and finds out the shortcomings of the current research in the field of engineering quality management,and points out the necessity of this research.Secondly,this study uses 4M1E theory and project life cycle theory to divide engineering quality into two dimensions,namely time dimension and system dimension.The analytic hierarchy process is used to construct the target layer,the criterion layer and the index layer of different dimensions,and then the two-dimensional model of highway engineering quality based on time dimension and system dimension is established.The expert voting method is used to solve the weight of the 2D model of highway engineering quality,and the optimal solution based on system dimension,time dimension and 2D model is obtained through calculation.Thirdly,the concept of influence degree based on refined management theory,also known as rooting degree,is proposed,and coupled with the two-dimensional model of highway engineering quality to solve the three-dimensional model of highway engineering quality management.The third dimension is from the management point of view.Influence the dimension.Mathematical methods are used to extract many optimal solutions for the 3D model of highway engineering quality management.Then,the project demonstrates that the 3D model of expressway quality management is applied to a certain section of SanXi Expressway,collects relevant data,establishes a three-dimensional model of refined quality management of a certain section of SanXi Expressway,and solves the model.Analyze and verify the validity of the conclusions of this paper.And put forward countermeasures and suggestions.Finally,conclusions and prospects.Firstly,the research questions and main conclusions of this paper are summarized.Secondly,the inadequacies of this research are pointed out,and further research directions are proposed.
