摘要: Synopsis The influence of a variation with depth Young's modulus on the stresses and displacements in an isotropic elastic half-space, subject to loading normal its plane boundary, is considered. case incompressible medium E(z) increasing linearly examined some detail. It shown that if E(0) = 0 loaded surface settles amount w0 proportional local intensity q applied pressure: q/ks where factor ks (the coefficient subgrade reaction) independent size or shape area equal numerically twice rate increase E depth. Outside does not settle. These results provide interpretation sub-grade reaction terms mechanical behaviour non-homogeneous continuum. Furthermore, this special components stress are be unaffected by E. On considere l'influence d'une avec la profon...
