摘要
某大桥多年来因自然条件堆积较厚海积流动性淤泥,最厚达40m。综合考虑工程地质情况及施工成本,上部结构现浇箱梁设计采用膺架钢管+贝雷支架作为支承承重体系,有效解决地基处理难度大、高支架稳定性差的施工难题,详细阐述膺架钢管+贝雷支架支承施工控制要点及注意事项。
A bridge has accumulated thicker marine fluidity mud due to natural conditions for many years,the thickness is 40 m. Considering the engineering geological conditions and construction cost,the falsework steel pipe and bailey trusses are adopted as support for box girders,which effectively solves the construction problem of difficult foundation treatment and poor stability of stent. The construction control points and notices of falsework steel pipe and bailey trusses are introduced in detail.
