A Study on the Layout and Carrying Capacity of Economical Arrival and Departure Yards in Suburban Railways of Beijing
In order to accelerate the development of suburban railways,the preferred strategy is to utilize existing railways.How to adapt to the transportation needs while reducing the demolition and renovation projects,reduce land use,and avoiding significant interference with the operation of existing lines and the surrounding environment is a key issue that needs to be considered in the decision-making of the entire line engineering plan,and also meets the requirements of improving resource utilization efficiency and accelerating the fundamental transformation of resource utilization methods.The article focused on studying how to minimize the scale of arrival and departure yards while ensuring the throughput capacity,in order to accumulate experience for similar engineering projects.The article analyzed the passing capacity of typical arrival and departure yards based on graphic method,and re-selected and validated the calculation parameters.The calculation model focuses on not only aligning with the current mature calculation theory of throughput,but also improving the efficiency of graphic method.After verification,under normal operating conditions,the plan of setting up 4 arrival-departure tracks(including the main line)at some stations and setting up 2 arrival-departure tracks(including the main line)at other stations on the sub central line of the Beijing suburban railway,can adapt to the predicted traffic volume.
