For the construction of the track foundation of fully automatic terminal storage yard under complex foundation condition,we put forward the test standard for the construction of sleeper and the ballast foundation of the terminal storage yard project,and establish the track construction technology and procedures based on the design scheme of the new U-shaped groove track.The monitoring results of parameters including the track elevation,span,inclination and flatness tolerance show that the proposed construction technology can ensure the accuracy of the track,and the settlement of track during operation is stable.The average settlement of 38#～53#storage yards is about 16 mm,and the maximum average settlement of all monitored boxes can be controlled within 80 mm.The construction technology of the track construction for the automatic terminal yard suggested in this paper can ensure that the track settlement during operation be controlled within the allowable range.
