Traditional tunnel monitoring practice measures the relative displacements between two measuring points. For complex three-dimensional tunnel excavation behavior, it provides limited information about the safety of tunnels, especially under the conditions of highly heterogeneous geology. To meet the demands of tunnel safety, a new scheme of data presentation is developed by Austrian scholars. It could reflect the deformation behavior around the excavation face according to the characteristics of different deformation curves. This paper introduces the methods of presenting the 3-D deformation data and their applications. It is hoped that the safety and quality of tunneling could be improved by applying better monitoring technique in our country.
