摘　　要：围岩变形是评价隧道结构稳定性的重要量化指标之一。针对常规围岩变形量测方法难以同时实现安全、快速、经济要求的现状,提出一种基于图像处理技术的新型围岩变形非接触量测方法,并对其理论推导、图像处理等关键技术进行研究和分析。通过现场试验结果表明,该法设备简单、经济,操作方便、快捷,测量结果精度较高,为我国围岩变形量测开辟了一条新途径。Deformation of surrounding rock is one of the important quantitative indicators for evaluating the stability of tunnel structure. In this paper, aiming at the state quo that conventional measurement for surrounding rock deformation is difficult to realise secure, fast and economic requirements simultaneously, we propose a novel non-contact measurement of surrounding rock deformation which is based on image processing technology. Furthermore, we also study and analyse the key technologies such as theoretical derivation and image processing, etc. Field test results show that this method is simple in equipment and economical, its operation is convenient, quick with quite high precision. It opens up a new way on measurement of surrounding rock deformation in our country.
