最近,荷兰铁路部门研究出了在松软的地基上铺设铁路轨道的新方法。荷兰要在其多沼泽的松软地基上修建高速铁路线路,必须开发新型层面轨道。该构造较轻并具有所需的刚度,其刚度来源于经过工业处理的放置在土里的硬化混凝土。对于车速为300千米/小时的列车,1.2米深的层面型无道碴轨道具有足够的刚度横越任何松软地带。而传统高速铁路线路上铺道碴型的轨道要求额外和昂贵的维护保养费用。无道碴轨道可能是很好的选择,因为它不仅减少对轨道 Recently, the Dutch railway department has developed a new method of laying railroad tracks on soft ground. In order to build high-speed railway lines on its boggy, soft ground, the Netherlands must develop a new level of orbit. The construction is light and has the required stiffness, with stiffness derived from hardened concrete placed in the earth after industrial treatment. For trains traveling at speeds of 300 km / h, the 1.2 m deep, ballastless track has sufficient rigidity to cross any loose zone. The ballast-type tracks on traditional high-speed rail lines require additional and expensive maintenance. Ballastless track may be a good choice because it not only reduces the number of tracks
