斜弯桥墩台轴线与桥轴线的偏差分析

Analysis on Deviation between Substructure Axis and Bridge Axis for Curved Skew Bridge

通过对某斜弯桥的施工研究,找出桥梁斜交角度、超高率、道路曲线半径及桥梁宽度等是桥轴线发生偏位的原因,并推导出偏差的计算公式。提出对此类桥梁的设计和施工需引起重视。

Based on the study of construction of a curved skew bridge,it is found out that the skew angle of bridge,rate of super-elevation,curve radius of road and bridge width etc are the causes of deviation of bridge axis.At the same time the calculation formulas for deviation have also been found out.It is proposed that more attention should be paid to the design and construction of such kind bridges.
