摘要
提出了一种新的盾构姿态自动测量方法,该方法通过全站仪测量盾构机上控制点坐标,结合双轴倾斜仪获取水平倾角数据,将两类观测值进行联合处理。在改进的七参数空间坐标转换模型的基础上,通过空间几何关系分析,建立联合平差模型。在实践中,基于该方法自主开发的全站仪与倾斜仪联合盾构自动导向系统已成功应用于上海地铁12线和杭州地铁1号线等隧道区间的施工导向,验证了该方法的可靠性和实用性。
This paper proposed a new computational method for shield attitude automalic measurement. It was through the treatment of the coordinate data of control points measured by total station and 2 horizontal inclination angles obtained by biaxial inclinometer. Using the improved large-angle coordinate transformation model with 7 pa rameters,a combined adjustment model was established via spatial geometry analysis. The method was implemented in self-developed automatic shield guidance system, and successfully applied to construction guidance of some subway projects like the construction of Shanghai Metro Line 12 and Hangzhou Metro Line 1, both of which proved the relia bility and practicability of this method.
