Quasi-Static Theory of Soil-Structure Interaction
This study treats the effect of the interaction between underground structures and the surrounding soil in reducing the loads transmitted to the structure, the so-called arching phenomenon. A continuum theory of soils proposed by G. A. Geniev is applied to a quasi-static, planestrain problem of arching. The basic partial differential equations are shown to form a hyperbolic set and are solved by the method of characteristics. Consistent stress and velocity fields are obtained. Comparison with available experimental results shows that the Geniev theory underestimates the surface pressure required for failure of an underground structure in relatively dense granular soils. The source of this difficulty is explained and an approximate method of overcoming it is presented. A simplified extension to a theory taking account of inertia of the soil and unsteady motions is treated in an appendix. (Author)
