摘要 以南堡疏解线特大桥跨越津山线工程为例,为保证临近既有铁路线路基的稳定性,提出了桥梁承台施工时钢板桩的防护措施,并阐述了钢板桩布置、计算及施工方法,指出钢板桩防护对于距离近、覆盖层厚的承台施工具有周期短、见效快、成本低、安全性高等优点。 Taking Nanbao Shu-Jie line extra-large bridge crossing Jin-Shan line engineering as an example, in order to guarantee the adjacent ex-isting railway subgrade stability, the paper puts forward steel-sheet pile protecting measures in bridge cushion cap construction, and describes steel-sheet pile distribution, calculation and construction methods, and finally points out advantages of steel-sheet pile protection for short- dis-tance and thick-covering cushion construction, such as short construction duration, fast efficiency, low cost and high safety and so on.
