摘要
对下承式钢管混凝土系杆拱桥的中横梁及系梁预应力施工,从预应力材料检验、张拉工艺、孔道压浆等方面详细阐述了各个环节的关键技术和核心难点,这些技术有效的保证了中横梁及系梁预应力施工质量。
As for the next CFST tied arch bridge in prestressed beams and tie beam construction, from the pre-stressed materials testing, tensioning process, pore-grouting, etc.. This paper described in detail all aspects of the key technologies and core difficulties. These technology effectively guarantee the prestressed beams and tie beam construction quality.
