This paper presents results of an elastoplastic finite element back analysis of a shallow tunnel through residual soils. The tunnel was constructed as part of the expansion of the underground transit system in the city of São Paulo, Brazil. A comprehensive laboratory testing program on undisturbed soil samples was performed in order to characterize the stress-strain-strength behavior of the residual soils. Results from this laboratory testing program were used to calibrate a nonassociateddoi:10.1061/(asce)1090-0241(2002)128:3(227) fatcat:reokq3zda5dp5jtf24fu2ekqde
