摘要
钢管混凝土拱桥具有桥型美观、跨越能力强、施工周期短等优点,是大跨径拱桥一种比较理想的结构形式。桥梁的施工控制是桥梁建设质量的保证,衡量一座桥梁的质量标准就是要保证桥梁的受力状态以及成桥后的线形符合设计要求,施工监控可以有效地衔接大跨径钢管混凝土拱桥的设计与施工,对大跨径钢管混凝土拱桥,必须进行施工控制。本文以桁架式钢管混凝土拱桥——蒲山大桥为工程实例,进行桁架式钢管混凝土拱桥施工监控技术研究,所做的主要工作和得出的主要结论如下:
1.对蒲山大桥进行了设计复核验算,计算结果表明,该拱桥各构件受力和变形均在桥梁设计规范规定范围之内,桥梁结构受力合理。
2.对蒲山大桥施工过程进行仿真计算分析,得到了拱肋混凝土的灌注以及拱肋支架卸架过程中的结构内力和位移,制定了合理的桥梁施工方案;给出了各主要施工阶段桥梁各构件内力和位移,提供了合理的预拱度和吊杆索力,计算所得结果对指导桥梁施工具有重要意义。
3.根据蒲山大桥的桥型特点和施工工艺,制定出详细的桥梁施工控制方案,进行了蒲山大桥的施工控制工程实践,从该拱桥的施工控制工作可以看出,蒲山大桥桥梁线形和内力符合设计要求,达到了桥梁施工控制预定的目的。
本文计算和实测结果已应用于蒲山大桥的施工控制实践中,指导了蒲山大桥的施工,确保桥梁施工安全并实现设计意图,取得了较好的效果。
The steel pipe concrete arched bridge has a beauty of bridge and crosses over the ability strong, start construction the period short etc. It is a favorable model for the long-span arch bridge structure. The construction control of the bridge is the assurance that the bridge constructs the quantity, measure a bridge of quantity standard be toes guarantee that the bridge is subjected to the deformation and the internal force state of each members of this bridge were within the specialized range of bridge design norms, the construction control can link up availably greatly design and constructions of across the path steel pipe concrete arched bridge, carry on the construction control towards acrossing the path steel pipe concrete arched bridge greatly, must.
The beam-arch assembled Pushan great bridge is set a project example in the paper.carrymg on the beam-arch assembled steel pipe concrete arched bridge construction control technique research, the main work do and get the main conclusion of as follows:
1. Carried on the design to recheck to check to calculate to Pushan great bridge, calculation result enunciation, both the deformation and the internal force state of each members of this bridge were within the specialized range of bridge design norms, so that the stress state of this bridge structure was rational.
2. Carry on imitating the true calculation analysis to Pushan great bridge construction process, get the concrete filled and the arch rib support unload the internal force and deformation of bridge, making up reasonable of bridge construction project; Give the each main construction stage internal force and deformation of bridge, providing to prepare the arch degree and the suspender force reasonablely, computing the income result to guide bridge the construction has the important meaning.
3. According to the characteristic and construction technique of the arch bridge, a detailed bridge construction scheme was made. By the practice of the bridge construction control, the deformation and internal forces of the bridge are under the design request. From the practice of the bridge construction control, the arch bridge has achieved the purpose of the construction control.
The computation and actually measure result of this dissertation had applied to the practice of construction of Pushan great bridge, guide the construction of Pushan great bridge, insure the bridge construction safety combine realization design intention, and obtained preferable effect.
