Question

铁路“三折”是指钢轨、辙叉和夹板的折断.“三折”威胁行车安全,危及人民生命、财产安全,是铁路运输安全的大敌,防止“三折”是铁路安全工作的重点之一,尤其是北方冬季安全工作的重点.因此必须认真分析“三折”产生的原因,采取积极对策加以防治,确保行车安全.
与任何其他工程结构一样,列车荷载与轨道抗力的相互作用关系决定了轨道的破损程度和使用寿命.按照目前国际上普遍采用的连续弹性基础梁轨道强度理论,影响轨道结构受力的因素主要有荷载、轨枕、道床和钢轨四个方面.
每年10月下旬至次年2月,是工务设备钢轨、夹板、辙叉最易发生折断的关键时期.针对这一问题,工务段应从掌握设备随季节变化的内在规律入手,认真总结近年来实现防断安全的经验,全面抓好防断措施的落实,超前做好防断各项准备工作,确保大动脉畅通.

Answer 1

Railway "TRIPLE" refers to rail, Frog and the splint broken. "TRIPLE" threat to traffic safety and endanger people's lives and property safety, the safety of rail transport of enemy prevent the "TRIPLE" railway safety, one of the priorities, particularly in the northern winter is the focus of security. Therefore must carefully analyze the "TRIPLE" the causes and take active measures to control and ensure traffic safety. And any other engineering structure, train load resistance with the orbital interaction between the decision to track the extent of damage and life. According to the current international row commonly used in the elastic foundation beam orbit strength theory, affected by the track structure of the factors for the main load, sleepers, ballast and rail four aspects. Annually in October to the end of February next year, Works rail equipment, splints, Frog most vulnerable to fracture the crucial period. In response to this problem, Public Works grasp of the equipment should change with the seasons start the inherent law. conscientiously sum up the defense continually achieve security, a comprehensive grasp break prevention measures are implemented, Anti-breaking advance do all the preparatory work to ensure the smooth flow of the great arteries.
