Abstract
The 4th Nanjing Yangtze River Bridge North Terminal Chuhe Bridge is a prestressed concrete composite box-girder bridge with corrugated steel webs constructed by cast-in-place cantilever method. In order to shorten the construction period, it takes the closure scheme which is under asymmetric constraint. In this paper the force and stress in each important construction stage under different closure schemes were analyzed. The results showed that the procedure of the closure method under asymmetric constraint is feasible.
