The evaluation of geotechnical parameters based on field test data is a promising procedure in geotechnical engineering. The use of numerical methods and optimization techniques allow these estimates to be made of a less subjective way. In that sense, this dissertation aims to develop a computer program which uses the finite element method (FEM) to solve mechanical problems of static equilibrium in two-dimension and axisymmetric conditions, incorporating optimization processes to make inverse analyses of field tests. The dissertation begins with a literature review on topics relevant to the subject studied. Following, the load test analyzed is presented as well as the methodology used. Finally, results that validate the computer program developed and results of the inverse analysis of the load test are presented. It is concluded that the method worked quite adequately and improvements are suggested to be made in future works.
