Deskripsi

Ground movements caused by the construction of tunnels and excavation are inevitable. Estimation of such movements is a very important for risk management in tunnel design. This paper presents a case study of ground settlements induced by twin shield tunnelling in Copenhagen using analytical and numerical methods and their predictions. The predictions are compared with the monitored settlements. The comparison shows that the predictions are sufficiently conservative.
