Solutions to Relative Problems in Design of Station Yard of Metro Vehicle Depot

Research purposes:Although the metro vehicle depot is generally located at the edge of the city,but the land is still in short supply.Breaking through the conventional design idea can effectively relieve the conflict between the design requirement and the short supply of land.Based on the actual project situation,this paper analyzes the various control sectors of occupation of land,such as occupation of lands by vehicle test track,by vehicle washing track and by arrival and departure track,for providing the reference to the similar design works.Research conclusions:(1)In the design,the old conventions should not be fettered and all elements should be analyzed reasonably.The design should be of safety,money saving,science,reasonableness and full meeting the demands of the operation.(2)The through vehicle washing track is installed on right side or left side of the arrival and departure track in accordance with the topographic conditions and plane layout of the throat area.(3)If the vehicle test track suffers from the limitations of the topographic conditions and occupation of land,the curve can be laid out in any area,but the radius of curve,the length and super-elevation of the transition curve should meet the speed requirement of vehicle test track,and the large radius of curve should be used as much as possible.
