摘要
结合某市钢管混凝土系杆拱桥的实际工况,通过钢管拱桥坐标测设、计算及钢管拱肋制作加工、采用临时支墩架设等施工工艺,对钢管拱桥拱肋施工线型控制进行了全面介绍,实践证明线型控制方法简单、方便、快捷,较好地处理了温度的不利影响。
With the practical construction conditions of the concrete-filled steel tubes-tied arch bridge of the Huai＇an Road in a certain city as a practical example,the linearity control of CFST arch bridges is overall dealt with in the paper through the coordinate measurement and calculations of the steel tube arch bridge, and the overall introduction to the production process of steel tube arch ribs and the use of temporary but- tress erection process for linearity control. Practice proves that the linearity control method is simple, convenient, fast, and satisfactory in overcoming the adverse effects of changes in temperature.
