| Abstract: | Based on the solution of J.V.Boussinesq,the calculation formula of additional stress in soil on the action of trapezoid distributed load is deduced through the method of integral calculus. Based on the obtained formula,the formulae of additional stress in soil on the action of rectangular load and triangular load are deduced by changing the original conditions. An application example is given.The presented method is very simple and better than that in the soil mechanics reference books in which the formulae seem to be separated and complicated. The method is feasible in practice and suitable for the calculation with programs. |
