Main and side arch construction method for flying swallow type half-through concrete filled steel tube tied-arch bridge
The invention relates to the field of tied-arch bridge construction, in particular to a main and side arch construction method for a flying swallow type half-through concrete filled steel tube tied-arch bridge. Through modeling calculation and analysis, on the basis that the disturbance influence on side arch cast-in-place concrete and an arch seat is within an allowable range when a main arch section is hoisted, the construction step of firstly constructing a side arch and then carrying a main arch is adjusted to a step of synchronous cross construction of main and side arches. Compared with a traditional process of first side arching and then main arching, the method can better adapt to the social environment and the natural environment, has wide application prospects and is worthy of application and popularization in construction of arch bridge structures of the same type.
本发明涉及系杆拱桥施工领域，具体涉及一种飞燕中承式钢管混凝土系杆拱桥主边拱施工方法。通过建模计算分析，在主拱节段吊装时对边拱现浇混凝土及拱座的扰动影响在允许范围之内的基础上，将先边拱后主拱的施工步骤调整为主拱边拱交叉同步施工。相比传统的先边拱后主拱工序，能够更好的适应社会环境及自然环境，具有广阔的应用前景，值得在同类型拱桥结构施工中推广应用。
