Abstract: The problems currently existing in the interfaces between urban rail transit depot and parking lot (hereinafter referred to as ′depot′) track engineering are summarized, optimization suggestions for professions include technical process, electromechanics, buildings and structures, stations and road bridges, environment evaluation proposed. The suggestions include: the column inner wall distance of the column inspection pit should be 1.1 m and requirements of technical process profession on different types of track bed length, rail length, washing rail gauge and bumper should be verified; problems that cause additional reconstruction such as missing rail-crossing pipelines pipelines and rail-crossing troughs, incorrect position of insulation joints should be avoid-ed; when adopting the design scheme of densifying the columns at the rail joint, it is necessary to reasonably determine the fastener spacing at the densified rail joint based on the fastener type selection to avoid contradiction between joint fasteners and rail joint clamp plate; the garage-front intercepting ditch should adopt a reinforced concrete structure, minimizing the width of the intercepting ditch as much as possible to control fastener spacing at this location, or reduce the elevation of the intercepting ditch cover plate and use a crossing plate cover plan; to improve the construction quality of the column, column construction can be completed by track profession in one time, or adopt the plan of adding an iron pad below the fastener with the pad partially embedded into the column, or a plan of column prefabrication; the station drainage ditch and cable well should avoid being covered by ballast; it is necessary to control the post-construction settlement of whole track bed to ballast track bed transition segment; when developing depot overhead property, it is necessary to predict and evaluate the environmental impact based on the overhead property business modes, to ensure that the track vibration reduction and noise reduction measures are economically reasonable.
