Abstract
Stress redistribution, ground loss and change of groundwater table in the course of
tunnel excavation cause surface settlements. These surface movements may damage structures
above and aside the tunnel. Experience shows that the timely and spatial influence of underground
excavations on the surface settlements varies in a wide range. The domain of influence mainly
depends on the ground properties, the quality and quantity of the tunnel support as well as on
tunnel dimension and the construction method (including additional measures like groundwater
lowering). In some cases the surface movements are limited to some meters ahead and aside of the
tunnel and stabilization is reached within a few days after excavation. In other cases an extended
surface area is influenced for a long period and the stabilization process is slow (Burland, 2001).
Sufficiently accurate predictions of surface movements are required in time to set up appropriate
countermeasures
