The design of the vertical elevation scheme for the site is an important part of the design of urban rail transit vehicle bases.The article analyzes the controlling factors of the site elevation of vehicle bases,analyzes the common vertical elevation schemes of the site of vehicle bases based on the vertical design theory,takes a certain parking lot as an example to analyze the topographical characteristics within the site selection range and the rela-tionship with other controlling factors in combination with the overall layout of the parking lot,conducts vertical design research on the site of the parking lot,and determines the vertical design scheme of the site with uneven heights in each area in the front area and the track area of the parking lot,which saves engineering investment on the premise of ensuring flood safety of the parking lot and meeting its requirements of production and operation functions.
