In optimal design, the minimum wall weight is treated as the objective function. Through design algorithm, the optimal design variables (base width, toe width, thickness of base slab and angle of front face) yielded minimum structural weight of the wall and satisfied stability conditions have been determined for different soil parameter values. At the end, a detail parametric study searching the effect of change of soil parameters on the re-taining wall design has been conducted with 120 optimized wall designs for different values; eight values of the angle of internal friction, three values of the unit volume weight and five values of wall heights. The obtained results from optimization anal-yses indicate that change of the angle of internal friction more effective than change of the unit volume weight on the optimal wall weight. Economic wall design with op-timization analysis is achieved in a shorter time than the traditional method.eninfo:eu-repo/semantics/openAccessİnşaat ve Yapı Teknolojisiİnşaat MühendisliğiMalzeme Bilimleri, Özellik ve TestArticle10.20528/cjsmec.2019.03.004
