Abstract Research purposes: The Nanjing South Station is of the structure with integrating the bridge with building．Lots of CFST were used in the Nanjing South Station． During the construction，there are many practical engineering problems because of the restrictions of construction site environment and construction conditions，so it is necessary to study construction technology of CFST． For the construction difficulties，such as one － time pouring height of concrete －filled tubular column ( maximum height of 18． 22 m) ，large diameter of tube ( diameter of 1 200 mm) ，erection and welding of tube along with concrete pouring alternately，control of liquidity and stability of CFST，the various quality assurance measures have been taken to ensure the successful completion of concrete construction．

Research conclusions: ( 1) For one － time pouring 18． 22 m CFST，the semi － self － compacting concrete or self －compacting concrete can be used． The artificial irrigation and high － frequency vibration must be conducted to the semi － self － compacting concrete in tube． ( 2) By selection of good raw materials of concrete，optimization of the match ratio and taking various quality assurance measures，the good liquidity stability of CFST can be ensured，therefore to ensure the CFST performance and quality． ( 3) In the site inspection for Nanjing South Station，the ultrasonic testing can accurately detect defects of CFST by sampling，so it can ensure CFST quality．

Key words： CFST liquidity volume stability ultrasonic testing
