摘　　要：横向贯通误差是特长隧道工程贯通测量质量的重要指标,文中以兰渝铁路西秦岭特长隧道左线贯通测量情况为例,在对特长隧道洞内平面控制测量布网方案、施测、数据处理等方面进行论述的基础上,通过数据处理和分析比较发现,将陀螺定向边作为约束条件参与平差计算得到的横向贯通误差,比未加测陀螺定向边可明显地提高精度。Lateral breakthrough error was the vital target of extra- long tunnel breakthrough survey quality.Taking the breakthrough survey in left tunnel of the West Qinling extra-long tunnel of Lan-Yu Railway line for example,in the paper,on the basis of discussing the distribution network solutions,surveying,data processing and other of plane control measuring in extra-long tunnel,precision of the lateral breakthrough error taking the gyroscopic orientation edges as the restrictions participating the adjustment calculation improved dramatically by comparing with the data processing and analysis.
