通过换铺或应力放散无缝线路地段的钢轨,在按规定垫好滚筒,抽掉滚筒处的跪下橡胶垫板等情况下,分析钢轨内部应力状态。再分考虑钢轨始端轨温和不考虑钢轨始端两种情况下,实际锁定轨温的情况。探讨出无缝线路钢轨就位之后和线路锁定之前,确定钢轨轨温的理论依据。 Through the shop or stress relief of seamless track lot of rail, padding in accordance with the provisions of a good drum, remove the kneeling rubber drum at the drum under the circumstances, the analysis of internal stress state rail. Sub-divided into consideration the beginning of rail rail mild rail without considering the beginning of the two cases, the actual rail temperature conditions. The theoretical basis for determining the rail temperature is discussed after the rail in the seamless line is in place and before the line is locked.
