摘　　要：随着高速铁路的快速发展,铁路部门对铁路轨道的平顺性状态参数要求日益提高。传统的手工拉绳法、弦测法和惯性基准法已不能满足轨道长波不平顺的测量要求。文章研究利用激光准直原理,通过激光长弦发射和数字接收光靶配合测量,直接对轨道的轨向和高低进行检测。该方法能直接测量出轨道的平顺性状态,提高测量精度,提高检测效率。With the rapid development of high-speed railway,the railway department to the rail track smoothness state parameter requirements are increasing.The traditional manual string method,chord measurement method and the inertial reference method can not meet the long-wave track irregularity measurement requirements.In the present study,the track alignment and height of track can be detected directly by using the principle of laser collimation and the measurement of laser long string emission and digital receiving light target.This method can directly measure the state of the track irregularity,improve the measurement accuracy,improve the detection efficiency.
