青藏铁路无缝线路试验段轨道参数试验

青藏铁路在技术可行地段铺设无缝线路，对于提高行车速度、减少线路齐护维修、降低运营成本，实现铁道部铁路跨越式发展战略，具有十分重要的意义。详细介绍了道床横、纵向阻力与轨道原始弯曲的试验方法和数据整理分析过程，获得了合理取值。确定在青藏铁路格望段通过规范的轨道施工，可以迭到铺设无缝线路设计参数的要求。另外，对青藏铁路轨道稳定性与钢轨强度进行了检算，并确定了锁定轨温。

Track's parameters of experiment in experimental section of Qinghai-Tibet railway

Laying CWR on manipulable locality of Qinghai-Tibet railway is important to raise the speed of train and reduce the cost of management. It also has important sense to the request of our country railway stride over development. The method of test and analysis on the data of ballast resistance, initial deflection were described carefully by the paper. The paper values of the design parameters were obtained. The require of laying CWR in Qinghai-Tibet railway was achieved by normative construction of track. Strength and stability of track were calculated and fastening-down temperature of rail was decided.
