摘要 国家将城市地下管廊建设作为我国城市基础建设的重点方向,其施工过程中的安全性至关重要。数字图像相关法的精度高,成本低,且操作简单方便,并能实现近程和远程的测量。本文引入数字图像相关法对天津市某工程地下管廊的周围土体位移进行监测。实验结果验证了数字图像相关法在管廊周围土体位移监测中的可用性,且该监测方法不影响管廊的正常施工。 The foundation of underground pipe in cities is presented as a key direction in urban infrastructure and its safety of construction is important.Digital image correlation method has the characteristics of simple operation,high precision and low cost and can be used in short-range and long-range measurement.In this paper,the method is introduced to monitor soil displacement of an underground pipe in Tianjin city.The experimental results show the usability of the method in pipe engineering is certified and the method doesn’t effect the pipe construction.
