Research On The Layout Of Passenger Station And The Setting Of Connecting Lines With The Linking-Up Of High Speed Railway And Existing Railway

High speed railway with the merits of fast speed, large volumn, high efficacy, high safety and low pollution is being developed forcely in China, which has the big function in accelerating the development of railway undertaking, strengthening the competitive capabilities for passenger transportation and relieving the pressure of existiong railway network. In China, high speed railway is constructed along the existing railway in parallel and linked up with the existing railway in the railway terminal. The paper studies the layout of passenger stations and the setting of connecting lines with the linking-up of high speed railway and existing railway by consulting relevant data at home and abroad, which gives the guidance to design and construction of high speed railway.Generally, the paper has done some work in the following aspects:Firstly, it analyzes the layout types of passenger station with the linking-up of high speed railway and existing railway, and rules of address-choosing of passenger station and its common methods of layout.Secondly, it studies the layout method of high speed railway with the linking-up of high speed railway and existing railway with two steps.Step 1: it studies the generation of layout scheme of passenger stations and builds 0-1 integer programming model.By calculating the model, the proper numbers of passenger stations and some superior layout schemes of high speed railway station and existing railway stations can be obtained. Step 2 : it evaluates the layout schemes, analyzes the main factors that affect the layout of station and builds the evaluation index system . By the evaluation index system with gray relational analysis ,the best layout scheme of high speed railway station can be choosen finally from the layout schemes of railway station in step 1.Lastly, it studies the setting of connecting lines with the linking-up of high speed railway and existing railway. It builds evaluation index system of the layout of connection line and chooses the best scheme in all the possible schemes with evaluation index system and analytic hierarchy process .
