长大直线隧道洞内控制测量资料的联合处理

Combined processing of the control survey data in long straight tunnels

通过理论推导并结合实际应用 ,提出了对长大直线隧道洞内各期平面、高程控制测量资料进行联合处理的新方法。该方法合理利用多期测量资料 ,且计算简单、方便 。

combining theoretical derivation and practical application, the author raised a new method of combined processing of the data of both plane and elevation survey at each construction stage of long straight tunnels. The method utilize survey data rationally, and calculation is simple and easy. It can effectively increase the accuracy of the control survey result in long straight tunnels.
