One of the common methods in slope stabilization is using drilled shafts. Designing Drilled shafts is based on resisting against loads due to lateral displacement of sliding soil mass to improve slope stability condition and causes decreasing in displacement at slope crest. The arching effect which has an important role in this kind of slope stabilization method has been investigated by using the load transfer factor definition. Load transfer factor Value is based on three- dimensional finite element parametric study. Numerous research has been carried out for studying this kind of stabilization, especially arching performance under static Condition. But a few of them have investigated seismic performance of arching phenomenon. Due to lack of research in this topic area, this research intends to study seismic performance of slopes reinforced with a row of drilled shafts and carry out a comprehensive numerical study using ABAQUS software to consider arching phenomenon and parameters affect arching. It was found that parameters which have the most effect on arching are pile location, pile length, slope angle, soil friction angle, pile center to center distance to diameter ratio, pile elastic modulus soil elastic modulus, pile cross section, dilation angle and friction angle between pile and soil, respectively. By using the results there will be the ability to quantify arching effect and consider it in limit equilibrium methods. Moreover, the effect of stabilizing piles on slope like decreasing settlement, soil amplification and from structural point of view, effects of these parameters on maximum bending moment in pile has been investigated.
