| dc.description.abstract | Sheet pile walls are one of the oldest earth retaining structures constructed to retain earth, water or any other fill material in civil engineering projects. They are used in a wide variety of both temporary and permanent building applications, including excavation support system, cofferdams, cut-off walls under dams, slope stabilization, water front structures and flood walls. Several methods can be used to increase the load carrying capacity of sheet-pilling walls. The use of additional anchored tie rods grouted in to the backfill soil and arranged along the exposed wall height is one of the most practical and appropriate solutions adapted for stabilization and rehabilitation of the existing sheet pile wall. In this work parametric study through the finite difference program, FLAC 2D, version 7was carried out to investigate the influence of construction procedure, grouted body area, length of grouted body, number of anchor and anchor inclination for multi-anchored sheet pile walls in terms of horizontal displacements and moment induced along the sheet pile wall. This study also provide in giving insight in formulating a guide line for specific type of soil by solving the deep excavation benchmark problem with a finite difference based program FLAC and using CY plastic soil model for the sand soil. The results indicate that for this kind of problem the advanced soil constitutive model (cap-yield plastic soil model) will give realistic deformation. And also the results of the analysis indicate that the optimum angle of anchor inclination is 27 degrees to reduce the maximum bending moment and the maximum horizontal displacement. Variation of construction procedure has a significant effect on the sheet pile wall. As grouted body area increases, the maximum horizontal displacement and the maximum bending moment decrease. As grouted body length increases for not pre stressed anchors, the maximum bending moment and the maximum horizontal displacement decrease but this trend of grouted body length become a complete opposite when the anchors become pre stressed.
