ProblemA concentrated load of 1000 kN is applied at the groundsurface. Compute the vertical pressure (i) at a depth of 4 m below the load, (ii) at a distance of 3 m at the same depth. UseBoussinesq's equation.Solve your self.8
WESTERGAARD'S FORMULA FOR POINTLOADSActual soil is neither isotropic nor homogenous.Westergaard, a British Scientist, proposed (1938) a formula for thecomputation of vertical stress б z by a point load, Q, at the surface asin which µ, is Poisson's ratio. If µ, is taken as zero for all practicalpurposes,The variation of / B with the ratios of (r/z) is shown graphically on next slidealong with the Boussinesq's coefficient IB. The value of I w at r/z = 0 is 0.32which is less than that of IB by 33 per cent.Geotechnical engineers prefer to use Boussinesq's solution as this gives9conservative results.
