Because of T-type rigid frame bridge pier top cast segments’ structure is complex,embedded parts,steel,each prestressing tendons and it’s channels,anchorage intensive staggered,force complex,greater difficulty of construction.So select the construction plan is very important,the quality of the program will directly affect the progress of the construction and the quality of construction. There are many options of stent design,most used is attached to the cantilever bracket.In this paper, several commonly used form of stent were introduced. |
