| Abstract: | When the precast I beam is tensioned,the lateral displacement tends to take place and will affect the installation,application and safety of the beam. For the lateral displacement,this article presents the pre control measure and the remedial method, which has been applied in the construction supervision quality control of an extra large bridge.In that case,the lateral displacement was controlled within 2 cm, which satisfied the requirement of the design and the criterion and achieved gool result. |
| Keywords: | prestressed concrete I beam lateral displacement pre control measD |
