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.
