Simplified Method of Active Earth Pressure for Special Inner Support Structure

Abstract:

A method is proposed for the calculation the earth pressure exerted on the inner wall of a special double-row support structure. The analysis shows that there is a pressure gradient between the walls and an amplification coefficient is introduced to reflect the increase of the earth pressure. The predicted and observed behaviors are compared to examine the feasibility of this method and the result shows that this method gives the closest prediction of the deflection of the inner wall.
