The use of a generalized graphical procedure based on numerous finite element solutions to evaluate the response of buried conduits is described. The proposed procedures include: obtaining the constrained modulus characteristics for both the in-situ soil & the compacted fill as functions of overburden stress by available methods; determining the equivalent homogeneous modulus characteristics as a function of overburdened stress; consider the response of interest to be that associated with the addition of fill above the crown; determine the average constrained modulus associated with the stress increase at the conduit centerline due to the addition of a layer of fill; determine the conduit flexibility parameter; obtain and compute the deflection, trust, and bending moment parameters for the layer; obtain the respective correction factors for tangential compression and finite cover height from the figures presented.
