高矮墩大跨度连续刚构桥施工控制研究

Research in Construction Control of Continuous Rigid Frame Bridge with Long Span and High-low Pipers

文章以翟家河大桥为工程背景,介绍了预应力混凝土连续刚构桥的施工控制原理和方法,阐述了墩高相差悬殊的连续刚构桥的施工控制要点。通过翟家河大桥施工控制的验证,论证了文中所述施工控制方法对高矮墩大跨度连续刚构桥施工控制的可靠性及实用性,最后对此类大桥的施工控制理论与方法提出了一些建议。

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.
