论文题目： 浅谈铁路常见病害及防治方法 中文摘要 铁路线路由于机车车辆的动力作用和自然条件对线路的影响，常年裸露在大自然中，轨道几何尺寸不断发生变化。路基、道床随时发生变形，线路设备不断机械磨损，计划维修、紧急补修和重点整治比例安排的不合理，维修方法不当，以及周期性的大、中修工作未能够及时进行，因而对铁路线路造成诸多病害。伴随着铁路跨越式发展战略的不断深化，宜万铁路实现了货物直通运输并开办集装箱运输业务的列车运行。在快速扩充运输能力，大大降低成本的同时，也相应地加剧了对铁路线路的破坏。导致钢轨、联接零件及轨枕不断磨损，线路设备、道床变化加快。道床脏污、板结、变形、翻浆冒泥等病害增多。 铁路线路设备是铁路运输业的基础设备。经常保持线路设备完整和质量均衡，是列车能以规定速度安全、平稳和不间断地运行，并能延长设备的使用寿命。合理养护铁路线路，及时有效的分析、预防和整治设备病害，为实现铁路跨越式发展，确保铁路线路质量是保障铁路运输安全的必要。 关键词：铁路线路 病害原因 预防方法 Abstract Railway lines due to the dynamic function of the locomotive and natural conditions on the lines influence, the perennial bare in nature, track geometry size change constantly. Roadbed, track bed occur at any time of deformation, the line equipment constantly mechanical wear, maintenance, and emergency plan includes the proportion of arrangement and key is not reasonable, maintenance method is undeserved, and periodically big, long work not be in a timely manner, and so for many diseases caused by the railway line. With the great-leap-forward development strategy of railway deepen ceaselessly, the railway should million realize the direct transport goods and open container transportation business train operation. Rapid expansion in transportation capacity, and greatly reduce costs at the same time, will be increased to the destruction of the railway line. Lead to rail, connecting parts and sleeper constantly wear, the line equipment, the track acceleration. The track, harden, deformation, smudgy abundant take mud increased disease. Railway line equipment is the foundation of the railway transportation equipment. Often keep the line equipment complete and quality balanced, was to train with the speed regulation of security, stability and continuous operation, and can prolong the service life of equipment. Reasonable maintenance railway line, timely and effective analysis, prevent and control equipment diseases, to realize leaping development railway, ensure the quality of the railway line is to ensure the safety
