Abstract

Mechanically stabilized earth walls are among the most commonly used soil-retaining structural systems in the construction industry. This study addresses the optimum design problem of mechanically stabilized earth walls using a recently developed metaheuristic optimization algorithm, namely adaptive dimensional search. For a cost efficient design, different types of steel reinforcement as well as reinforced backfill soil are treated as discrete design variables. The performance of the adaptive dimensional search algorithm is investigated through cost optimization instances of mechanically stabilized earth walls under realistic design criteria specified by standard design codes. The numerical results demonstrate the efficiency and robustness of the adaptive dimensional search algorithm in minimum cost design of mechanically stabilized earth walls and further highlight the usefulness of design optimization in engineering practice.

基于自适应维数搜索算法的机械稳定土墙经济高效设计

机械稳定土墙是建筑行业中最常用的挡土结构体系之一。本研究采用一种新发展的元启发式优化算法，即自适应维数搜索，解决了机械稳定土墙的优化设计问题。为了节约设计成本，不同类型的钢筋和加筋回填土被视为离散的设计变量。通过标准设计规范规定的实际设计准则下的机械稳定土墙成本优化实例，研究了自适应维数搜索算法的性能。数值结果证明了自适应维数搜索算法在机械稳定土墙最小成本设计中的有效性和鲁棒性，进一步突出了设计优化在工程实践中的实用性。

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
