Abstract
In urban areas, there are many high-rise buildings founded on grouped piles. In the grouped piles, a row of loaded piles can be considered as continuous embedded wall for two-dimensional analysis. It is questionable for physical behaviour of the wall if the tunnel construction progresses adjacent to such loaded existing wall. In this study, the author has conducted a series of two-dimensional model tests and numerical analysis to investigate the wall movement and soil behaviour below the tunnel centre line due to tunnelling in granular ground condition. It is found that the behaviour of wall is mostly influenced by relative geometric condition between tunnel and wall positions, and ground volume loss due to tunnelling.
