【摘要】 为提高地铁隧道贯通测量的精度,通过对陀螺全站仪的工作原理进行分析,介绍并比较了我国国产陀螺全站仪的现状及特点,结合高精度陀螺全站仪在某城市地铁隧道贯通中的工程实例,得出加测陀螺边定向测量后地铁隧道贯通精度将大大提高的结论,从而保证地铁工程建设的顺利进行。更多还原

【Abstract】 In order to improve the measurement accuracy of subway tunnels through,and by analysis of the working principle of Gyro Station,this paper analyzed the status and characteristics of China’s domestic Gyro Station. And through the practical application of high-precision Gyro Station in a city’s subway tunnel through,this paper drawn conclusion of that after plus the Gyro Station surveying,the subway tunnel through directional measurement accuracy would be greatly improved. Thus to ensure the progress of the subway projection conducting smoothly.更多还原
