盾构姿态自动导向及多源数据融合处理方法
A New Method of Shield Attitude Automatic Measurement and Multi-source Data Processing
摘要
Abstract
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.关键词
