盾构刀具磨损是影响盾构施工质量和进度的关键问题,带压换刀作业的安全风险大、费用高昂、作业工期长。目前常规的刀具磨损检测方法存在风险大、效果不佳、精确度不够等缺点,而摄影测量技术的发展为盾构刀具磨损检测提供了新的思路。文章结合泥水盾构隧道施工特点,将摄影测量技术应用于盾构刀具的可视化检测中,利用经过三维控制场标定的摄像装置,采集盾构施工中刀具的影像数据,通过与盾构精密三维模型的定向操作,借助三维可视化平台和影像分析对刀具的磨损情况进行定量检测,实现了盾构刀具虚拟可视化集成显示和磨损情况的数字化评估。该研究成果为实现盾构刀具磨损检测提供了理论基础和软件支持,具有一定的经济效益及工程意义。

Cutter wear is a key problem that affects construction quality and the progress of shields due to the high-risk, high-cost and long operation period of hyperbaric intervention. Aiming at the disadvantages of common detection methods, such as high risk, poor effects and low accuracy, and combined with the characteristics of slurry shield tunnelling, this paper proposes a new visualized detection method for shield cutters based on the development of photogrammetry technology. By using this new method, image data of shield cutters may be collected during construction via a video camara calibrated by a 3D control field. With directed operation of the precise 3D shield model, a quantitative detection can be conducted in terms of cutter wear conditions by utilizing the 3D visualized platform and image analysis, thus making possible the virtual integrated display and digital evaluation of cutter wear.
