Open publisher page 1 citations

Abstract

To study the active earth pressure of retaining wall with multiple layers of cohesive soil,based on the hypothesis of sliding plane and methods of mathematics and mechanics,a formula is proposed considering the cohesion force on sliding surface and the adhesive force on interface of retaining wall.A program is designed for the formula.A calculation sample shows the diversity of calculating results with or without the consideration of the cohesion force c on sliding surface and the adhesive force cw on interface of retaining wall,and the diversity increases with the rising c and cw.The formula is reliable and easy to be applied to projects.
