摘要
传统的接触式量测方法虽然具有成本低、简便可靠、能适应恶劣环境等优点,但对施工干扰大、测量速度慢,难以满足隧道施工测量要求。因此在围岩大变形段落,采用全站仪无尺法及隧道图像识别系统相结合的方法,可以快速、安全、实时地对围岩进行监控,确保施工安全。
The traditional contact measurement methods are low in cost,simple and reliable,able to adapt to bad environment and so on,but the construction interference is large,measurement speed is slow,it is difficult to meet the measurement requirements of the tunnel construction. Therefore,in large deformation of surrounding rock sections,using the method of total station instrument without ruler together with the image recognition system,it can quickly and safely monitor the surrounding rock in real-time,thus ensures the construction safety.
