铁路部门在最近几年经历六次大提速。为了适应这一趋势,更有效的利用既有铁路的资源,在铁路建设方面一般采取对既有线改造的方式。在既有线改造中,为了缩短建设周期,最大程度的减小施工对铁路正常运营的影响,平改立工程一般都采取顶进方法来施工。着重介绍了这几年在京沪线、沪昆线铁路顶进涵施工中碰到的问题及处理方法。
The railway sector has experienced six major increases in speed in recent years. In order to adapt to this trend, it is more effective to utilize the resources of the existing railways and generally adopt the method of rebuilding existing railways in terms of railway construction. In the reconstruction of the existing lines, in order to shorten the construction period and minimize the impact of construction on the normal operation of the railway, the general plan of reforming and rebuilding projects has taken a top-down approach to construction. The problems and solutions encountered in the construction of the culvert in the Shanghai-Kunming railway in the past few years are mainly introduced.
