摘要
高速有砟铁路调试运营初期,轨道设备易发生病害,主要表现为TQI值飞速增涨、线路不均匀沉降、长波高低层出不穷、道岔尖轨侧弯频出等。轨道质量病害直接影响了列车的运行安全,为确保运行初期线路的安全稳定性能,本文通过对铁路运行初期轨道病害检测方法、TQI均值管理应用分析、主要病害整治技术三个方面进行分析,探索了高速有砟铁路运行初期轨道设备的维护整治原则,有效降低设备病害发生的同时,可作为施工阶段轨道精调质量的考量和借鉴。
The disease of track equipment was easy to occur in the early stage of commissioning and operation of ballasted high-speed railway. The main manifestations are rapid increase of TQI value, uneven settlement of the line, endless occurrence of long wave height, side bending frequency of the fork rail, etc. Rail quality disease directly affects train safety. In this paper, the detection method of railway diseases in the early stage of railway operation, TQI mean value management and application analysis, and the main disease control technology are analyzed. This paper discusses how to maintain and renovate the track equipment of ballasted high speed railway at the beginning of operation, iIt can be used as a reference for the track fine adjustment during the construction period while effectively reducing the occurrence of equipment diseases.
