钢管混凝土单圆管拱桥拱轴线偏差分析

摘要

分析了竖向和横向不同形式的拱轴线偏差对钢管混凝土单圆管拱桥成桥阶段的影响,结果显示,竖向反对称偏差的影响比其他类型偏差的影响大,指出钢管混凝土拱桥施工控制时,拱轴线的偏差峰值可使用现有规范的允许值。%The paper analyzes the impact of single round tube arch bridge with steel-tube concrete at bridge-forming stage, studies of vertical and horizontal styles upon arch axis deviation. Results show that: the impact of vertical anti-symmetry deviation is larger than any other deviation. While the construction of steel-tube arch bridge iscontrolled, the top arch axis deviation value is within the regulated scope.
