摘要
环行道的高速试验是在小半径， 大超高， 大欠超高下进行的， 有着其特殊意义。在线路整正的过程中， 使用了大型养路机械， 并针对大型养路机械的特点， 采用多遍作业以消除轨道几何尺寸偏差， 平轨及打磨以消除轨道短波不平顺； 线路开通后， 一次提速达到２００ ｋｍ ·ｈ－ １。试验运行表明， 对轨道几何公差控制是适宜的， 接触网改造也是成功的。
An unusual high speed test was conducted on the Loop Track under the conditions of small radius,big superelevation and large deficiency of superelevation.In reconditioning the existing loop track,heavy maintenance machines were used,and multiple passes of machine operations were carried out to eliminate deviation of geometry,to smooth up the track surface and direction,and to grind the track rails to eliminate short wave irregularities.At the same time,the catenary was reconstructed into an automatic adjusting,elastic catenary shape,suspension structure.The records of the test held later showed the track deviations were properly controled and the catenary construction was satisfactory under 200 km·h -1 running speed.
