摘　　要：针对隧道空间狭小,全站仪难以对盾构机上2个以上点进行测量,提出利用智能全站仪、双轴电子倾斜仪组合导向控制技术,在三维直角坐标转换模型的基础上将双轴电子倾斜仪测定的盾构机的俯仰角和扭转角作为观测值参与平差,解决了多源数据采集、导向数据联合处理的问题.上海地铁12线、杭州地铁1号线等区间隧道的施工导向实践证明,该方法可靠、实用.A new method was put forward for shield-attituded automatic measurement. Due to the narrow space of underground tunnel and the difficulty in measuring more than 2 points by robotic total station, an integrated guidance method by robotic total station and clinometer was employed, then with the pitch and scroll of shield obtained from clinometer as observed data, the error adjustment was made based on 3D datum transformation, which solved multi-source data collection and process. The proposed method was successfully applied to the tunnel construction guidance of Metro Line 12 in Shanghai and Metro Line 1 in Hangzhou, which proved to be reliable and practical.
