Title: SENSITIVITY ANALYSIS OF CANTILEVER CONSTRUCTION OF CONTINUOUS BOX GIRDER BRIDGE
Abstract: In this paper,taking the continuous box girder cantilever bridge construction as an example,in the construction of monitoring the sensitivity of the design parameters were analyzed. The reaserch objects are main beam weight,elastic modulus of concrete,concrete shrinkage and creep and temperature changes that affect the internal forces on the bridge and the design parameters. Finite element analysis software of bridge-Doctor Bridge is adopted to establish a simulation model,to carry on the structural response analysis,to prestressed concrete continuous box bridge construction. We make a conclusion that the main beam weight and concretes` shrinkage and creep are the main parameters. Moreover,prestressed and annual temperature are the secondary parameters.
