各种类型的旅客站台是客运部门最常见的一种建筑物。按技术性能,它们中的许多站台已不能适应当前的要求并需要改建。由于大规模的改建工程必然会给列车运行带来严重影响,因此必须尽量缩短站台改建期限,这在列车运行紧张的区段尤为重要。在许多线路上,铁路站台的改建工作需要用5～8个月的时间,这是绝对不允许的,因为站台改建工程主要是在“天窗”时间内进行,一个“天窗”的持续时间一般为1.5～3h,
Various types of passenger platforms are the most common type of structure in the passenger transport sector. According to the technical performance, many of them can no longer meet the current requirements and need to be rebuilt. Due to the large-scale reconstruction project will inevitably have a serious impact on train operation, it is necessary to minimize the station alteration deadline, which is particularly important in the tension of the train section. It is absolutely not allowed to rebuild railroad stations on many routes over a period of 5 to 8 months. This is because station reconstruction works are mainly carried out within the time of “skylights”. The duration of a “skylight” is generally 1.5 ~ 3h,
