This paper attempts to investigate the concept of forces acting on sheet pile installed in sliding slope. A new analytical formulation is proposed to reinforce the sliding slope. The equilibrium equation is formulated, and a new relationship is proposed to calculate the force exerted on the sheet pile. When the slope is stable the minimum force and moment are exerted on the sheet pile; however, when the slope starts to move the moment and force exerted on the sheet pile are increased. A reduction of 5 kPa in cohesion increases the force exerted on the sheet pile by about 180 kN/m. By reducing the friction angle by 5 degrees, the force exerted on the sheet pile is increased by about 50 kN/m. The proposed analytical formulation is shown good agreement with numerical analysis.
