OPTIMUM WHARF TYPE IN SOFT SOILS; A CASE STUDY FOR MAHSHAHR

Selecting the best alternative between different wharf types depends on many items such as hydrodynamic conditions, soil layers, bathymetry of the area, requireddepth and etc. A gravity quay-wall may be appropriate for an area with high bearing soil strata, yet the selection is not always such simple. It seems that both sheet pileand piled jetty can be used in soft cohesive or sandy soils. Which one is better Proper answer helps to make a good decision at the initial phases of the project thatdecrease the project time and costs accordingly. Because of the coastal sedimentation phenomena, existence of soft soils at the upper layers is a common practice near the shorelines and the north-west part of the Persian Gulf is covered with mud [1]. In this study, numerical method is used to investigate the functionality of sheet pile in soft soils i.e. soft clay and loose sand.
