铁路路基翻浆冒泥病害机理及整治

由于每年降雨的冲刷,导致路基基床翻浆冒泥这一现象已成为影响铁路安全和运营的顽疾,每年需花费巨资整治路基翻浆冒泥,严重影响了线路的正常运营和铁路的大提速。文章在探求路基翻浆冒泥的机理的基础上,对现有病害探测和维修检测的方法进行了分析,并对现有路基基床翻浆冒泥整治技术进行了对比研究。对比分析表明:路基翻浆冒泥是多个影响因素共同作用的结果,但同时不同路基翻浆冒泥产生的原因也有差别,因此,在对路基翻浆冒泥病害的整治中应具有针对性。

The mechanism of mud pumping in railway subgrade and its treatment measures

The illness of road foundation is the mud and grout problem of bed foundation,which is dues to rainfall erosion every year,It spends huge sums of money on renovating mud pumping,which has bad influents on railway safety and improvement of train speed.Based on the mechanism of mud and grout problem of bed foundation,the methods of disease exploration,the maintenance examination and the cure technology are studied comparatively in this paper.The comparative analysis show that the frost boiling and mud pumping is the result of effect of multi-factors,and details of the the applicability of renovated technique are also given along with available repair recommendations for different influence factors.
