Abstract:

The construction of tunnels in urban areas may cause ground displacement which distort and damage overlying buildings. Shield tunnelling is a commonly used construction technique because it is very effective jn reducing ground deformations and thus damage to urban infrastructure. Prediction of ground settlement is considered as highly significant in the design of tunnels located in urban areas. City metro tunnels are usually constructed as twin-parallel tunnels and their adjacent construction may lead to surface deformation, affecting the surface environment and the safety of the tunnels. This paper presents the analysis of ground settlements induced by a construction of twin tunnels.
