随着重载铁路、客运专线和城际铁路的迅速发展,铁路线路日常维护检测工作变得越来越重要,而且工作量大,技术要求越来越高。传统的线路维护检测方式和技术已很难适应当前铁路的发展步伐,面临着巨大的挑战。通过介绍国外铁路线路维护检测先进技术和装备,为提高我国铁路维护检测工作效率和准确性,以及建立状态修等新型铁路维修体制出谋划策,以解决繁忙运输与线路维护检测之间的矛盾。 With the rapid development of heavy haul railway, passenger dedicated line and intercity railway, the daily maintenance and testing work of railway lines has become more and more important, and the workload is heavy and the technical requirements are getting higher and higher. The traditional ways and techniques of line maintenance and inspection have been difficult to adapt to the current development of the railway and face great challenges. By introducing the advanced technology and equipment of railway line maintenance and testing in foreign countries, this paper provides suggestions for improving the efficiency and accuracy of railway maintenance inspection in our country and establishing a new railway maintenance system such as condition repair to solve the contradiction between heavy traffic and line maintenance and inspection.
