Abstract
In this study, both the model test and the numerical analysis were carried out to figure out the physical behaviour of the model pile during the tunnelling. As a result, both the vertical and the horizontal displacements were simultaneously occurred in the model pile which is subjected to the working load during the volume loss. Consequently, the phenomenon of inclination took place in the model pile. The degree of inclination of the model pile depends on volume loss due to tunnel excavation, pile tip's offset from the tunnel centre, and bearing ground conditions in which pile tip is located. Therefore, in the planning stage of urban tunnelling not only the ground behaviour with respect to the pile locations, but also the physical behaviour of pile itself should be carefully analysed to avoid damage of adjacent buildings.
