摘要
某大桥工程设计为自锚式悬索桥,其主塔截面外轮廓是柱式主塔、四面凹槽,顶部4.5 m圆弧过渡变截面。通过对异型截面主塔的施工实践,从模板方案选择、模板设计、模板施工、施工控制措施方面进行了阐述。实践证明,该施工方案可行、可靠,并具有较好的经济性。
A bridge project is designed as self-anchored suspension bridge, with the cross section outline of the main tower is of column type, four-side groove, are transition cross section 4.5 m on the top. Through the construction practice of the main tower on the deformed cross section, detailed elaboration is made on formwork plan choice, formwork design, form- work construction, construction design measurement, etc. , which proves that the construction plan is feasible, reliable, and economically acceptable.
