Abstract: <br /> <br /> <br /> <br /> <br /> The aims of this research is evaluating the effect of berm size and strength in limiting deformation as a temporary restraint toward sheet piles before the next construction, particularly in basement construction. The analysis case is an excavation of a basement with LX32 sheet piles. <br /> <br /> <br /> <br /> <br /> The analyzed soil is dense sands consist of 4, = 32 derajat and c = 1 kN/m where the soil modeling is Hardening-Soil applied as data input for Plaxis Program. Dimensions of berms are limited by changing the slope of the berms as 1:2, 1:3, and 1:4. The berms used in the analyses are assumed to be triangular and trapezium in shape. Also, in order to establish limiting behavior, a no berm case and a horizontal berm case are analyzed for each excavation. The wall is assumed to either fully penetrate (fixed end wall) also partially penetrate (free end wall) the sand layer. <br /> <br /> <br /> <br /> <br /> The results demonstrate that increasing berm size serves to decrease movements of wall systems and vertical displacements behind wall systems. However, the effects of the berm are not a unique function of the berm size. It is also influenced by wall stiffness; excavation depth, wall end conditions assumption and soil shear strength. The safety factor of wall-soil system decrease as the berm slope steepened. Restraint force of berm as passive force for the wall-soil system can control the stability of-sheet piles wall effectively. Contribution of berm as passive restraint force on sheet piles wall for analyzed cases between 49.5%-99.8%. <br /> <br />
