Parametric investigation for discrete optimal design of a cantilever retaining wall

Abstract: In this paper, discrete design optimization of a cantilever retaining wall has been submitted associated with a detailed parametric study of the wall. 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 det… Show more

“…Other parameters are the soil properties such as unit volume weight and angle of internal friction. Changes in the unit volume weights during optimal design do not affect the optimal weight values significantly; thus, γ soil = 18 kN/m 3 was selected as the mean value [22].Analysis parameters are the same for all CRW numerical analysis in GEO5 (Table 2).…”

“…The optimum weight of the cantilever retaining wall by HSA has been obtained as Wwall = 59.4kN/m for Ør =40° and γr=18kN/m 3 with considering static load case in another literature study [29]. For the same design case, the optimum wall weight has been obtained as 181kN/m with considering dynamic loads in this study (Ør=40° and γr=18kN/ m 3 ).…”

“…Optimum designs of cantilever retaining walls have been acquired by many researchers utilizing metaheuristic optimization algorithms inspired by nature [3][4][5][6][7][8][9][10]. The dynamic load effect in cantilever retaining wall design is a situation that should be considered for designs to be made in earthquake zones.…”

“…Therefore, new techniques are developed based on the advancing information and computer technologies to design retaining walls, considering the optimization of sizing and cost. Optimization methods are one of the technique that is used to design retaining walls effectively and nowadays there performed lots of studies to possess the most useful and cost-effective method to design wall systems [7,8,9,10,11,12]. In this study, an optimization algorithm is used to predict optimum dimensions of L-Shaped retaining walls via minimum cost achievement against the change of soil geotechnical properties.…”
