COMPARISON BETWEEN SINGLE AND DOUBLE ANCHORED SHEET PILES WITH SIMPLIFIED APPROACHES TO SOLVE THE STATICALLY INDETERMINATE SYSTEMS

Abstract

The paper studied a case of anchored sheet piles that exposed to surcharge loads at different distances from the wall. Experimental works were conducted on two different systems of single and double anchored sheet pile walls. Also, numerical simulations were performed on both systems using PLAXIS. The experimental and numerical results were compared. The comparison showed the advantages of using double anchored sheet pile instead of single anchored one. It was found that a large reduction occurred in the values of maximum bending moments in the double anchored system, in addition to a significant reduction in the values of anchor forces. This paper also produced three simplified approaches aiming to solve the statically indeterminate system of double anchored sheet pile exposed to surcharge loads placed at different distances from the sheet pile wall.
