| Abstract: | Taking an overlong bridge of express railway as the engineering background,the article analyzes and studies the linear monitoring technology of cantilever pouring continuous beam bridge according to the theoretical forecast and the measured data,and discusses the main factors,i.e.pre-stressing,temperature,deadweight and so on influencing the bridge linearity in the course of construction.The analysis result makes clear that the pre-stressing,segment deadweight,section rigidity,temperature and creep are the ... |
