Abstract
In this paper a general numerical approach is proposed for the identif ication of loads acting on tunnel linings made by shotcrete, as a temp orary lining, and concrete as a permanent one so as to form a system o f monitoring and dimensioning these linings. This method requires a se t of in situ displacement measurements of shotcrete layer for back cal culation, and the constitutive relationship of the structural material s which are shotcrete, and concrete here is assumed to be linear elast ic. The advantage of this method is that it avoids those complicated c haracteristics of rock masses and the loads from back calculation can reflect the combinative effects of rock surrounding the tunnel. An exa mple was demonstrated for this method.
