The retaining walls are one of most types of engineering constructions and it have built from natural stones before discovering concrete, Where natural stones have considered one of the early human materials used in building engineering constructions for thousands of years, and many facilities in ancient civilization still existing effects so far, And after the discovery of the concrete and reinforced concrete, the retaining walls which was built from natural stones diminished relatively Despite the years this retaining walls has not lost its luster and brilliance, and there is increased interest in recent years in using new building material which consists of manufactured stones where used together with traditional construction materials in several areas both in geotechnical engineering or building … Etc . This retaining walls present simple technical solutions and it is desirable for aesthetic reasons and simple implementation and resistance to external conditions, In addition to being economical solutions limited cost compared to traditional reinforced concrete retaining walls. This research deals with the study of the behavior of Segmental Stone Retaining Walls (SRW) under the static and dynamic loads and parametric study of the most important factors which influence stability of these retaining walls.
