A systematic robust design optimization methodology is presented in this study for cantilever retaining wall backfilled with shredded tire in the face of earthquake hazards. Regarding the merits of application of shredded tire backfill in seismically active areas, the uncertainties in properties of this material (e.g., friction angle and cohesion) as well as uncertainties in earthquake load (e.g., peak ground acceleration) necessitate examining the robustness of design along cost efficiency in geotechnical design procedures. The wall tip deflection was treated as the response of concern for which a response surface was developed based on the design and random (uncertain) variables. Coupling with Monte Carlo simulations, the optimization in terms of cost and standard deviation of response as a measure of robustness yielded a set of preferred designs, or Pareto front, and the final optimal design was determined via selection procedures based on knee point concept.

在这项研究中，提出了一种系统的鲁棒性设计优化方法，用于面对地震危险时用碎轮胎回填的悬臂式挡土墙。关于在地震活跃地区使用切碎的轮胎回填的优点，这种材料的性能不确定性（例如，摩擦角和内聚力）以及地震载荷的不确定性（例如，峰值地面加速度）必须检查沿设计的稳健性岩土设计程序中的成本效率。壁尖挠度被视为关注的响应，基于设计和随机（不确定）变量开发了响应表面。结合蒙特卡洛模拟，
