Taking a practical engineering proj ect as reference,wet connection construction method of simply supported box beam segmental of Pulandian Gulf large Bridge in Harbin-Dalian railway is in-troduced,and the Huazi River south terminal bridge box beam segmental cementing construction method of the north bridge approach in the 4th Nanjing Changjiang River Bridge is also introduced. The two kinds of construction process are summed up and compared from the aspects of construction period,appearance,economy and practicability,and provides experience for the similar bridge con-struction.
