| Abstract: | Heigou Bridge is a prestressed concrete continuous rigid-frame bridge,its main span is 150m.In order to ensure the bridge linearly and force can accord with design,the process of construction has to be monitored.In this paper,establishing a simulating model with finite element method to simulate the process of construction and trafficed,researching the cantilever construction process and analyzing the structural deformation,stresses and internal forces,and comparing the results with those actual measurement records and they are consistent.It is meaningful for the bridge construction control. |
| Keywords: | rigid-frame bridge construction control simulation finite element |
