Abstract
The paper describes the design methods and summarises the results of the analyses for the recent NA TM excavation of an underground station of the Athens Metro. The non-linear finite element calculations show that for the excavation method used (twin side-wall galleries and a central pillar), the settlements at ground surface are very sensitive to the assumed values of the ground properties as well as the excavation sequence and construction details; it is shown that the settlements can be reduced significantly by increasing the number of the excavation stages and the density of the temporary support measures.
