轨道控制网平面偏移误差对高速铁路轨向平顺性影响的研究
|
摘要
对实测的高速铁路CPⅢ点位数据进行偏移假设试验,分析测站内多个CPⅢ点位发生偏移时对轨道精调数据及轨向平顺性的影响。研究表明,CPⅢ点坐标变化会直接影响调轨设站坐标,进而对轨向的精调偏差产生影响,CPⅢ点位变化越大,距离设站点越近,其对轨向的影响也越大。对于单个测站范围内的CPⅢ点位坐标,其在规定的限差范围内变化时,对测站范围内轨道10 m弦和30 m弦的轨向平顺性变化影响非常小。对于多个测站,当测站所观测的CPⅢ点在规范限差范围内变化时,300 m弦内每150 m轨向偏差与变化前的轨向偏差最大值为4. 54 mm。
This paper carried out the migration hypothesis test of the measured high-speed railway CPⅢ point site data,and analyzed the influence of the migration of multiple CPⅢ points on the track fine tuning data and track regularity. The research shows that the change of CP Ⅲ point coordinates will directly affect the coordinates of the total station,and then affect the precision deviation of the track direction. The greater the change of CPⅢ coordinates,the closer the station is,the greater the impact on the track direction. For the coordinates of CPⅢ points in the range of a single station,when they change within the prescribed range of tolerance,they have little effect on the track smoothness of 10-m and 30-m chords in the range of the station.For multiple stations,the maximum deviation of track direction per 150 m in 300-m chord is 4. 54 mm when the CPⅢ point observed by the stations varies within the range of the specification limited difference.
