| Abstract: | Based on Zhai Jiahe Bridge,the paper introduced the theory and methods of construction control in prestressed concrete continuous rigid frame bridge, and came up with some key-points of the construction control in the continuous rigid frame bridge with pipers in extremely different height.The effective construction controlling in Zhai Jiahe Bridge illustrates the reliability and practicability of the control methods the paper comes up with.Finally,some suggestions are proposed about the construction control in prestressed concrete continuous rigid frame bridge. |
| Keywords: | continuous rigid frame bridge cantilever construction construction control |
