Abstract: Taking Zhenpinglu Depot of Qingdao metro Line 5 as an example, the site of which is restricted by multiple structures and buildings, a variety of two-way line connection schemes with receiving and departure functions are proposed based on an analysis of the functional requirements of the depot entrance and exit lines. Then, through quantitative analysis of each connection scheme by using the weighted evaluation method, a connection scheme that can reduce the train empty driving distance and the operation cost is finally determined, it can also take into account the needs of property development above the depot.
