摘　　要：地铁线路弯多、半径小、通视长度受限,使高铁精密测量技术在地铁的实用效果上打了折扣。厦门地铁经过近年运营线路的检验,发现仍有部分区段存在国内地铁常见的抖动、晃车和噪声现象。为探索提高城市轨道交通工程轨道平顺性的有效办法,本文通过误差分析、仿真实验和工程验证相结合,研究提出三联架轨道控制网,采用控制网置平,比现有的城市轨道交通工程测量规范的任意设站轨道控制网平顺性更优。研究成果不仅对城市轨道交通工程有实用价值,对高铁和普铁工程测量规范的制定也有参考价值。Owing to the metro lines with a great quantity of curves,minor radius,and limited inter-visibility length,the practical ap-plication effect of high-speed railway precision measurement technology in the metro lines is usually unsatisfactory.By the inspection of Xiamen operating metro lines in recent years,it is observed that there are still some pervasive on-site phenomena of tremble,sha-king and noise in partial sections of domestic metro.In order to explore effective methods to improve the metro track irregularity,the research is conducted by using a combination of error analysis,simulation experiments and engineering verification in this paper.The track surveying control networks with station-to-station observation is put forward.Furthermore,their measurements data processing technique is given by soft fixed points and analysis of control networks adjustment.Studies have shown that this method has better reg-ularity than the method with free setting station in Code for Urban Rail Transit Engineering Survey.These researches would be helpful to the design and implement of track surveying control network in urban railway transit engineering,and probably useful in the formula-tion of track surveying control network of Code for Engineering Survey of High Speed Railway and Code for Railway Engineering Survey too.
