| With the development of Passenger-Dedicated railway construction, the large-scale railway stations emerge rapidly in many major cities.The scale of the stations in these cities have become increasingly prominent. Railway station currently built are all of big scale with over 18 tracks,some are even 30 tracks.The paper discussed how to determine the scale of Passenger-Dedicated railway large scale passenger station based on the problem,researched a great deal of literature,combined an actual example.The concent includes several points as follows:First, the technical operation processes and the relevant time in the large scale passenger station are disscussedSecondly,the layout of large scale passenger station yards are discussed,and the advantages and disadvantages analysed.Then the necessity of large scale station yard divided into two yards is demonstrated through quantitative and qualitative methods.Thirdly,this paper focus on how to determine the scale of large scale passenger station yards, calculational methods have been researched on the quantity of the arrival and departure tracks for common speed train are summarized,the existing methods are used to determine the scope of quantity of the arrival and departure tracks,based on the analysis of the fluencing factors,and to establish the multi-objective optimization model with the quality of passenger service consideration,then this paper designs simulated annealing algorithm and uses C++ language based on MFC to solve each model.Meanwhile,a new method used to calculate the quantity of the arrival and departure tracks was put forwordThe models adopted by the two methods are tested to be an effective method by determining the quantity of the arrival and departure tracks of NanChang west passenger station.Finally,this paper analyzes the factors influencing the platform scale and improves the existing calculation method,the queuing theory is applied to solve the model based on waiting mode on the platform. |
