| Abstract: | Base on midspan closure by incremental launching of the Jialing River bridge on Chongqing. Emphasis on calculation analysis of jacking force before closure up,and adjusting the force during incremental launching according to actual measured data. Stimultaneously introduce to the keys of construction monitoring on measuring data. Hope to offer some suggestion and experience to similar bridges. |
