  轨道
  track
    铺设在铁路路基上,用以直接支承机车车辆和引导机车车辆运行的结构物。
    结构 轨道一般由钢轨、轨枕、联结零件、道床以及道岔等组成。
    钢轨 常用碳素钢或中锰钢制造,其断面为工字形,用以承受机车车辆的车轮荷载,并将承受的荷载传给轨枕;同时为车轮的滚动提供连续、平顺的表面和引导车轮运行,这种轨道部件称为钢轨。在电气化铁路和自动闭塞信号线路上,钢轨还可兼作电路导体。钢轨的种类通常以每米钢轨的重量表示。中国铁路的钢轨有每米60、50、45、43公斤等种类。在使用英制单位的国家钢轨有码132、112、90磅等种类。不同种类的钢轨适用于不同的铁路线路,主要是依据线路上运行的机车车辆的轴重、行车速度、线路运输量等选用,如轻型铁路可采用每米重量较小的钢轨,有的轻型铁路采用每米仅10余公斤的钢轨;重型铁路可采用每米重量较大的钢轨,美国宾夕法尼亚铁路采用每码155磅的钢轨。
    工字形钢轨主要由上部的“轨头”和下部的“轨底”,以及连接轨头和轨底的“轨腰”组成。钢轨断面的设计,除考虑它的抗弯能力、轨头的抗压和耐磨能力、轨底的支承面积以及抗倾倒能力等强度和稳定性因素外,还须考虑经济合理性和轧制技术可行性等因素。中国铁路各型钢轨的主要尺寸如表1 中国铁路各型钢轨主要尺寸。
    各国铁路钢轨的标准长度是不同的。如美国钢轨标准长度为11.9米(39英尺);联邦德国为45米或60米;中国为12.5米和25米。另外,钢轨还有缩短轨,比标准长度缩短40、80、120、160毫米等数种,主要用于铺设曲线线路轨道
    钢轨必须具有足够的强度、韧性和耐磨性能。如果钢轨发生断裂和破损,将危及行车安全。钢轨的断裂和破损多数发生于有缺陷的轨头、轨头与轨腰连接处以及螺栓孔周围等处。钢轨断裂处一般有疲劳源,断裂呈脆性状态。钢轨生产时如有未切净的残余缩孔或有害偏析,使用时也可能造成轨腰劈裂。
    轨枕 铺设在道床和钢轨之间,用以承受从钢轨传来的力和振动,并传给道床;同时用以保持钢轨轨距和方向,这种轨道部件称为轨枕。轨枕除将钢轨传来的力振动传给道床外,它本身也能吸收部分振动能。每公里铁路线路上铺设的轨枕数,是根据线路上的机车车辆运行速度和运输量等因素确定的。机车车辆运行速度高和运输量大的线路铺设轨枕数多。中国铁路在直线线路上每公里一般铺设轨枕1840、1760和1600根。轨枕按材料性质分为木枕、混凝土枕和钢枕三种。
    ①木枕,又称枕木。世界各国铁路用木枕铺设的轨道约占轨道总长的70%。木枕的优点是弹性好,易于铺设,与钢轨的联结比较简单,绝缘性能好;缺点是使用寿命短(如易腐朽、易机械磨损及劈裂)。
    制作木枕的木材必须坚韧而有弹性,常用山毛榉、橡木、松木等木材制作。木枕经防腐处理后称为油枕,可延长其使用寿命。木枕尺寸因木材种类、产量以及所承受荷载不同而不同。中国铁路木枕大多数是用松木制作,干线上的木枕长2.5米、横截面为矩形,截面的底宽为22厘米、高为16厘米。
    ②混凝土枕,又称砼枕。第二次世界大战以后,混凝土枕开始大量采用,它的优点是稳定性好,使用寿命长,养护维修费省;缺点是重量大、弹性及绝缘性能差,在轨底部分须设缓冲绝缘垫层等。
    混凝土枕的主要类型有整体式预应力钢弦混凝土枕、整体式预应力高强度钢筋混凝土枕和钢杆式混凝土枕等。中国自1958年以来,主要推广使用前两种类型。
    ③钢枕。优点是抗腐菌侵蚀,抗白蚁和虫蛀;缺点是易受化学性腐蚀,不绝缘,维修费用高。钢枕仅在联邦德国和瑞士的一些铁路上,以及地处热带的一些
