Recent Tendencies in the Use of Optimization Techniques in Geotechnics: A Review

Abstract

The use of optimization methods in geotechnics dates back to the 1950s. They were used in slope stability analysis (Bishop) and evolved to a wide range of applications in ground engineering. We present here a non-exhaustive review of recent publications that relate to the use of different optimization techniques in geotechnical engineering. Metaheuristic methods are present in almost all the problems in geotechnics that deal with optimization. In a number of cases, they are used as single techniques, in others in combination with other approaches, and in a number of situations as hybrids. Different results are discussed showing the advantages and issues of the techniques used. Computational time is one of the issues, as well as the assumptions those methods are based on. The article can be read as an update regarding the recent tendencies in the use of optimization techniques in geotechnics.

Mono-objective Optimization of Retaining Wall Using Genetic Algorithm

“…It has been demonstrated that most of the techniques used are based on metaheuristic methods, but the Genetic Algorithm GA and the Particle Swarm Optimization PSO (optimization by surface modification) have been widely used compared to other methods and appear to effectively treat the non-linearities encountered in many geotechnical problems [20]. Therefore, the application of the genetic algorithm is highly recommended (Table 1).…”

“…Boumezrane carried on, optimization according to different deterministic and stochastic optimization schemes by a selection on a mathematical basis, of the objects best suited with respect to defined criteria, by choosing values or input functions within a certain range of parameters. It can be mono-objective (a single function) or multi-objective (several objective functions), sometimes even contradictory (Pareto optimization) [20]. Even though the weight and the cost of the task do not have opposing goals, the cost of the work increases as its weight increases.…”

Optimized Workflow Framework in Construction Projects to Control the Environmental Properties of Soil

“…The method proposed in this article is inspired by the optimization techniques of soil treatment [83][84][85][86][87]. The main idea is to factorise the parameters that affect soil properties into sub-classes having linear and non-linear distribution of data over time for various soil samples.…”
