Abstract

The measurement of ground deformation plays a key role in the laboratory experimental model work. In this study, the close range photogrammetric technique was used to measure the ground deformation subjected to the model tunnel excavation and then it compared to FE numerical analysis. Also, comparison between steel pipe reinforced model tunnel and unreinforced model tunnel was carried out. Consequently, the measured data can be converted to displacement vectors and contours through the image processing.
