Abstract:

Sheet pile wall system is considered one of the oldest common earth retention systems used in civil engineering projects. The common methods used in the design of sheet pile walls were based on the limit equilibrium approach using active and passive earth pressures. These methods - based on force and moment equilibrium- don't consider wall deformations, which are very important for achieving serviceability. An extensive parametric study was made through the finite element program, PLAXIS version 8.6 to investigate the behavior of inclined anchored sheet pile walls, studying the effect of changing wall penetration depth, and inclination of ground surface for different sand soil types, effect of ground water table and number of anchors on wall. to show the effect on horizontal wall displacements, anchor force and maximum wall bending moments for all cases. The minimum set of values of the wall penetration depth, unbonded length and bonded length satisfied the requirements of the instructions of (FHWA). Analyses were performed using the finite element method. The analysis results show that for penetration depth it was found that the maximum bending moment decreases significantly with the increase of penetration depth. And the anchor force decreases with the increase of wall penetration depth. Also, the horizontal displacement decreases slightly with the increase of penetration depth. On adding two rows of anchor, a significant reduction in maximum wall bending moment is noticed with a percent more than 55%, 45% and 38% for dense, medium and loose sand respectively. For ground surface inclination it was found that the maximum horizontal displacement, maximum bending moment and anchor force increase with the increase in ground surface inclination. On adding another row, the maximum bending moment is reduced by 48%, 43% and 37% for dense sand, medium sand and loose sand respectively. On taking ground water table in consideration for both sides, the maximum bending moments are reduced by 29%, 30% and 39% for dense sand, medium sand and loose sand respectively. Also, anchor forces are reduced by 24%, 25% and 34% for dense sand, medium sand and loose sand respectively
