一、概况基床翻浆冒泥病害在列车作用下,蔓延扩大,直接影响轨道结构的稳定,威胁列车安全运输,而且削弱基床承载能力,导致线路沉陷,造成整治困难。随着运量的增长,列车密度和行车速度也不断增加,因之基床翻浆冒泥也日益严重,据1985年8月秋检统计,津浦正线 I. Overview Bed boring mud and mud disease in the train, the spread of expansion, a direct impact on the stability of the track structure, the safety of train transport threats, and weaken the bed load-bearing capacity, resulting in subsidence lines, resulting in remediation difficulties. With the increase of traffic volume, the train density and driving speed are also increasing, so bedrock misting is also increasingly serious. According to the statistics of autumn inspection in August 1985, the positive line of Jinpu
