Abstract

The rapid development of urban areas due to population and infrastructure growth has led to increased traffic congestion, greater demand for residential space and environmental issues. One solution for these problems is the development of underground space, especially tunnelling. However, tunnel collapse causes significant damage, so it is important to understand the interactive behaviour of soil-structure-tunnelling in urban areas. This study uses a model test to investigate the behaviour of an embedded pile and the surrounding ground due to tunnelling in soft ground. Tunnelling is simulated by volume loss (V _L ), and soil deformation is observed according to V _L using close range photogrammetry and image processing. These data are compared by 3D numerical analysis.
