摘要
河北京张高速公路祈家庄大桥是一座大跨径预应力刚构-连续组合弯梁桥。该桥主梁现浇段大、工期紧,对施工挂篮提出了较高要求。对大跨度刚构-连续组合弯梁施工的新型三角挂篮、弯梁施工线型控制、0号梁悬臂托架段施工、1号~1号梁段无托架施工、合龙与体系转换等关键技术进行探讨。
The paper introduced a kind of new triangle hanging basket in the construction of a highway bridge of long span rigid frame-continuous curved beams,the construction technology of beam segment No. 0 and No. 1 and the closure segments,the linear control technology of curved beam.
