摘要
针对公路隧道地面传统控制测量方法的缺点，提出了利用全站仪同时进行平面控制测量和高程控制测量以建立隧道地面三维控制网的方法。结合高等级公路隧道工程实例，详细地阐述了三维控制网合理布设的原则、方法及其地面控制测量误差对隧道贯通误差的影响。
The method integraed the horizontal control survey with levelling survey for establishing the three dimensional ground control network of the high grade highway tunnel simultaneously using Total Station is presented to replace the conventional method of the tunnel ground control survey. It can overcome the shortcomings for the horizontal control survey and elevation control survey respectively. Three examples of the tunnel control networks are given to show the arrangement principles and the arrangement method of three dimensional control network and/or its value on the national main trunk expressway from Beijing to Zhuhai.
