Lateral stresses caused by uniform rectangular area loads on a cross-anisotropic backfill Available to Purchase

Surcharge loads applied to the backfill of a retaining structure produce additional lateral stresses that, for working load levels, can be predicted using the theory of elasticity. These surcharge loads might arise from wheels, railway tracks, highway pavements or foundations of adjacent buildings, and could be modelled as point loads, line loads, strip loads or area loads. In a conventional elasticity calculation the backfill material is assumed to be a homogeneous, linearly elastic and isotropic continuum. Nevertheless, numerous studies have recognised that the elastic properties in the horizontal and vertical planes might be different. Hence the effect of anisotropic deformability...
