摘要
随着城市建设规模的扩大,被铁路隔断的市政道路已经制约了当地经济发展和影响着老百姓出行,为打通道路和确保列车运营,需要采取箱形桥顶进技术。结合既有铁路下穿立交顶进工程,介绍了相邻两个斜交箱形桥的顶进方案优化、大坡度顶进及确保列车安全通行的技术措施。
With the expansion of the city construction, the municipal roads of railway partition has already restricted the lo- cal economic development and influenced people＇ s travel. In order to open up the road and ensure train operation, the box bridge jacking technology needs to be taken. This paper, combined with the existing railway underpasses jacking project, introduces jacking scheme optimization of two adjacent oblique-crossing box bridge, large-slope jacking and the technical measures to ensure the train safe passage.
