连拱隧道衬砌裂缝的三维监测研究

Three-dimensional in-situ monitoring for the cracks on a multi-arch highway tunnel lining

文章从发生方向、部位、宽度以及形成机理等方面对连拱隧道衬砌裂缝进行了分类,并简要介绍了隧道衬砌裂缝的监测方法以及三维裂缝监测的监测原理。最后,结合一连拱隧道实例介绍了隧道衬砌裂缝的三维监测方法和监测结果。

This paper classifies the cracks on multi - arch highway tunnel linings in terms of the developing direction, location, width of cracks and the mechanism of their formation, and then introduces some in - situ monitoring methods and the principles of three - dimensional in - situ monitoring for the cracks. The paper introduces a practical example of the three - dimensional monitoring for the cracks on the multi - arch highway tunnel lining.
