摘要
重载运输加层加剧了轨道结构的负担和路基的破坏。由于列车密度的加大,维修作业时间的减少,使线路质量下降。我国铁路一直沿用的周期性维修养护制度已不适应目前铁路发展的需要,必须逐步过渡到状态修养护制度。文章从研究的主要内容和应用情况进行了阐述。
Heavy-haul transportation puts more burdens on track and causes rail bed to deteriorate. Due to the increase of the train desity and decrease of maintenance time, the quality of the track comes down. The existing system of periodical maintenance could not cope with the requirements of development of the railway transport and it has to be based on the condition instead. The paper decribes the main contents of the research work and its application.
