Abstract

Abstract

Construction monitoring has been widely used in long-span bridges construction of high-speed railway.Combining with the construction monitoring of Jinghang Grand Canal(75 + 125 + 75)m prestressed continuous beam,it is introduced some key technologies and application methods of the deformation control and stress control,including: setting of the camber,determination of the bailey truss deformation,deformation prediction based on probability analysis,stress analysis of sensor data,analysis of temperature effect and controlling method,etc.it is done a calculation of concrete continuous beam deformation control.It is proved by construction practice that the monitoring results are satisfactory,which show the reliability and applicability of this monitoring method,which also provides a reference for similar bridge construction.
- long-span continuous beam,
- construction monitoring,
