Construction Technique Of Linjiangmen Cable-stayed Bridge In Jilin

The cable-stayed bridges are of large across ability and good structural performance. This kind of bridge has developed rapidly in our country in recent years. In this paper, the construction techniques of Linjiangmen cable-stayed bridge in Jilin, such as large sinking well technique of pier, climbing form panel technique of main tower, stay rope formwork traveler technique of girder and construction control, are summarized in details.Firstly, the engineering conditions include the general layout, structural form, meteorological phenomena, hydrological data, geological conditions of Linjiangmen cable-stayed bridge in Jilin are introduced. The bridge is of 685.711m overall length and of 625m mian bridge. The main pier of the bridge is reinforced concrete sinking well structure. The construction techniques of sinking well and explode in water are introduced. Auto climbing form panel technique is applied in the construction of main tower.Secondly, the construction techniques of cantilever concreting method of girder are analyzed in details. The construction program of stay rope formwork traveler, including the selection of formwork traveler type and the design of formwork traveler, is introduced.Finally, the construction management control of the cable-stayed bridge, such as control program, control aims, error control and the usage of monitor machine are introduced.
