The effects of relative depth of foundation on the vertical superimposed stress in subgrade |
| |
| Abstract: | Based on the Mindlin's elastic formula, a practical theoretic formula for calculating the vertical superimposed stress under the circular area with uniform distributed loading is presented,which makes the data table easily. The vertical superimposed stress is much influenced by relative depth of foundation.In this paper, some conducting meaningful concepts and views were obtained.It is theoretically and practically important to improve the present method for calculating superimposed stress and foundation deformation. |
