摘要
针对川藏铁路沿线气候环境恶劣、地形起伏大、跨越高烈度地震区等特点,综合分析复杂外部环境可能引起的跨区间无缝线路钢轨纵向力集聚、长大坡道线路不均匀爬行、地震作用下线路损坏、无缝线路长期服役等问题,提出跨区间无缝线路设计应重点关注的研究内容。①线路纵向阻力是影响跨区间无缝线路的基础参数,无缝线路设计应充分考虑线路纵向阻力的非线性、环境敏感性。②应结合川藏铁路沿线地形、地质特点,开展少维修无缝道岔结构研究,延长道岔服役寿命,并对大坡道无缝线路受力、地震作用下无缝线路状态等开展研究。③应开展轨温、钢轨纵向力、大坡道地段钢轨爬行、特殊桥上无缝线路等长期监测研究。④研究结语可为川藏铁路跨区间无缝线路关键技术研究提供参考。
According to complicated environment conditions along Sichuan-Tibet railway includes harsh climate,varied topography and high-intensity earthquake area,a serious of problems of continuous welded rail(CWR),which include rail longitudinal stress concentration,asymmetrical track creeping on long heavy down grade,track damage under earthquake and long-term service of CWR,were discussed.Researches need to be focused on of CWR in Sichuan-Tibet railway were also proposed.① Track longitudinal resistance is a fundamental parameter of CWR,and nonlinear longitudinal resistance and environmental sensitivity of track should be taken full account of in CWR design.②Combining with terrain and geological features along Sichuan-Tibet railway,researches including low maintenance welded turnout structure,track mechanics on long heavy down grade,CWR state and its stability under earthquake should be carried out.③ Long term CWR monitoring technology of rail temperature,rail longitudinal force,track creeping and interaction between track and special bridge should be conducted.④This paper can provide a reference of the research of CWR in Sichuan-Tibet railway.
