Study On The Site Selection And Layout Planning Of The Comprehensive Station Of The Expressway Project In S Province

In recent years,the development of China’s highway gradually accelerated,its coverage has gradually increased,especially since the 14 th five-year plan,China’s modern comprehensive transportation development of the main indicators officially released to the outside world,among them,the construction of expressway occupies an important position.In the process of expressway construction,it is very important to integrate materials and carry out pre-treatment to transport the processed building materials to various construction demand points.Among them,the improper site selection and layout of the complex station are the problems faced by most highway construction projects,resulting in a series of problems such as high construction project costs and redundant material transportation routes.Therefore,according to the characteristics of the project,it is an urgent problem to select the site of the expressway construction project complex station and to make reasonable internal layout without wasting the operation cost.In this paper,the site selection and layout planning of integrated field station are studied,and the main research contents and achievements of this paper are as follows:(1)Firstly,this paper analyzes the relative research methods of site selection and internal layout planning,and gives the research route and innovation of this project.According to the characteristics of the site selection and layout planning of the S Province Expressway Project Complex Station,the project data are sorted out through the field investigation,the mathematical model is created and compiled by lingo software to get the optimal set of site selection points for the integrated field.(2)According to the demand of site selection,the area of each functional area is calculated,and the bi-objective mathematical model is established according to the constraint condition of the area.Then,using MATLAB as a tool,particle swarm optimization algorithm was used to solve the optimal layout of integrated field stations.In this paper,by solving the model of site selection and internal layout planning of s province expressway construction project,the problems of subjectivity of the existing site selection method and simple division of site layout are improved,at the same time,the solution proposed in this paper also provides a certain reference for other highway project decision-making.
