铁路线路维护检测技术应用综述

Comprehensive Review on Railway Track Inspection and Maintenance Technologies

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 fast development of heavy haul railways, passenger dedicated railways and intercity railways, daily inspection and maintenance work for railway track is becoming more and more important, the work load is heavier and heavier, the technical requirements are higher and higher. Traditional Inspection and maintenance method and technology for railway track could not keep up with the development pace of railways, and face great challenges. After introducing the advanced technologies and equipments used for railway track inspection and maintenance in other countries, the paper tries to contribute to the improvement of China railway track inspection and maintenance work efficiency and accuracy, and gives reference for the establishment of new maintenance system such as status-based maintenance, in order to solve the conflict between busy traffic flow and railway track inspection and maintenance.
