摘要
在考虑轨道稳定性的过程中,要考虑鼠洞对轨枕的危害性。鼠洞会使轨枕底与道碴之间存在空隙,列车运行时鼠洞会使轨枕产生附加动力。对轨枕进行了动力学计算和强度校核,当鼠洞严重时,轨枕不能满足动力学强度条件。本文就鼠洞对轨枕的危害性进行了研究,介绍了大瑶山隧道治理鼠洞的实验,该实验效果较好,提出了治理鼠洞的基本方法,本文的研究结果为改进鼠洞对轨枕的危害提供了一定的科学依据,具有一定的指导意义和应用价值。
In process of consideration to track stability, will consider harmfulness of rat hole of the sleeper for railway. Rat hole will produce a crevice between the leeper for railway rails and ballast, when train in motion, will produce an additional motive power on the sleep. It is accomplished on dynamics calculation and strength proofread to the sleeper, while the rat hole is serious, the sleeper can not satisfy the dynamics strength. In this thesis, the author research the harmfulness of rat hole of the sleeper for railway rails, introduced an good experiment on the control of rat hole in the Yao mountain tunnel. Puts forword an effectual method of control the rat hole. This research finding has provided the basis for the control of rat hole, has reference and applied value.
