Tóm tắt:

In the past few decades, shield tunnelling machines have been used to drill in increasingly difficult geotechnical conditions such as soft ground like soft clay. The construction of tunnels in urban areas may cause ground displacement which distort and damage overlying buildings. Shield íunnelling is a commonly used construction technique because it is very effective in reducing ground deformations and thus damage to urban inírastructure. Prediction of ground settiement is considered as highly signiíicant in the design of tunnels located in urban areas. There are signiíicant discrepancies between empirical solutions to predict surĩace settlement trough because of different interpretations and database collection by different authors. In thiồ paper, the shape of settlement trough caused by tunneling by different approaches, namely analytical solutions, empirical solutions and numerical solutions by the finite element method.
