Study On Optimization Of Highway Route Scheme Based On Matter Element Analysis Model

Route scheme of highway construction comprehensive selection is an important issue to be resolved in the earlier stage of the highway construction,whether the basic approach to plan selection is scientific and reasonable,directly affect whether the project will meet the national economic construction needs after the completion of the project.It is related to whether the project can achieve the desired effect.Therefore,in the initial period of highway construction,the economic,technological,environmental and social evaluations of alternative route programs must be carried out,research on decision-making method feasible to apply to highway construction and basic trend of scheme selection,select the overall effect of optimal and feasible scheme to be implemented.This paper uses case analysis,the research object is Changde city of Hunan province in yuan li fast trunk line selection of the 7th avenue project,this article introduces and analyzes the highway selection process in China.Based on the characteristics of highway construction,the influence factors influencing the choice of highway route plan are analyzed.By analyzing the various factors affecting the project of highway line selection,and then optimization model of highway route planning based on physical element analysis is constructed,Through optimizing the model from economic rationality,construction convenience,energy conservation and environmental protection,social influence and other aspects,a relatively scientific and reasonable optimal route plan is considered,and through the structure optimization model of Changde city of Hunan province in yuan li line selection of the 7th avenue project is optimized and K solutions for the optimal solutions are obtained.Finally,the K scheme is evaluated comprehensively from economic evaluation,project operation analysis and social evaluation to get the feasibility and necessity of the implementation.According to the general rules and influence factors of highway line selection project,combined with the actual engineering conditions and environmental characteristics of the project,using the mathematics method,matter element analysis method to select the best route scheme of highway.Greatly reducing the limitation and blindness in the selection of the scheme are beneficial to the scientific and economic development of the highway route selection project.
