随着国内高速铁路的建设发展,无砟轨道广泛应用.无砟轨道长轨更换施工技术的研究迫在眉睫。通过以沪宁城际高铁长轨更换施工为例,总结运营条件下高速铁路无砟轨道长轨更换施工技术,对该技术加以分析阐述,为高速铁路养修提供参考。
With the construction and development of the domestic high-speed railway, the ballastless orbit is widely used, and the research on the construction technology of the ballastless track long-rail replacement is imminent. Taking the replacement of Shanghai-Nanjing intercity high-speed railway long-track as an example, the article summarizes the construction technology of the replacement of long-track of ballastless track on high-speed railway under the condition of operation, analyzes and elaborates the technology, and provides a reference for the maintenance of high-speed railway.
