Description

Because deformations are important indicators of the degree of stability during construction of rock structures, monitoring of deformation is a key element of construction of tunnels and structures for the underground research laboratory. Especially in the construction and maintenance of underground excavation, monitoring of deformations is needed for obtaining useful information to control its stability. We have been developing the application of digital photogrammetry to monitoring techniques in rock structures. Photogrammetric process has undergone a remarkable evolution with its transformation into digital photogrammetry. Photogrammetry has the advantage of measuring deformation of an object by some photos with easy measurements and excellent cost performance. In this paper, we present that the digital photogrammetry can monitor the displacements of the underground excavation accurately along with a capability of real-time measurement. (author)
