| Abstract: | The paper analyzes the mechanism of action and deformation for piles and soils among piles.On the basis of compatible deformation condition between piles and soils among piles,the quantitative formula is acquired about soils among piles how to distribute upper loads,the formula mechanics concept is simple.Finally,the paper expounds calculation process and method through a engineering example.Calculation shows the effect that soils among piles bear upper loads is obvious under adaptable conditions. |
