Summary In this paper a general numerical approach is proposed for the identification of loads acting on tunnel linings made by shotcrete, as a temporary lining, and concrete as a permanent one so as to form a system of monitoring and dimensioning these linings. This method requires a set of in situ displacement measurements of shotcrete layer for back calculation, and the constitutive relationship of the structural materials which are shotcrete, and concrete here is assumed to be linear elastic. The advantage of this method is that it avoids those complicated characteristics of rock masses and the loads from back calculation can reflect the combinative effects of rock surrounding the tunnel. An example was demonstrated for this method.
