It is particularly true when soil model is necessary to assess soil behaviour [Meieret al., 2008]. Nevertheless, it is not always efficient to directly assess the values of all the parameters in the case of soil mechanics. Considering structural mechanics, [Li et al., 2007] also worked to propose an optimal design of a truss pylon respecting the stress constraints of the elements but it is not an easy task to solve considering the number and loading of the structure. Inverse analysis is an efficient solution to reach these aims. This technique becomes more and more popular thanks to the increase of the computing capabilities. Computing costs have decreased and allow to handle complex optimization problems through meta heuristic methods for example to ide
