Engenharia geotécnica, tendências emergentes, necessidades das sociedades humanasResumen
A engenharia geotécnica é um dos primeiros domínios técnico-científicos a intervir em qualquer projeto de infraestruturas ou de desenvolvimento urbano, sendo, muitas vezes, o mais importante. No decurso dos tempos muitas inovações metodológicas, analíticas, numéricas e tecnológicas foram sendo descobertas e utilizadas nas investigações de campo e de laboratório e nas áreas da análise, do projeto e da construção de estruturas geotécnicas. Os campos em que a geotecnia tem forte intervenção e onde essas inovações foram sendo introduzidas são muito vastos e espraiam-se por escalas muito diversas. A globalização mundial, a utilização não sustentável dos recursos, as alterações ambientais causadas por razões antrópicas, o aumento dos desastres naturais e a carência de infraestruturas para dar resposta às necessidades das populações criam um quadro que condiciona decisivamente a evolução da engenharia geotécnica. Neste conjunto de quatro artigos perspetiva-se o futuro da geotecnia: parte-se de uma caracterização, feita no 1º artigo, das diversas condicionantes, tanto sociais, económicas e ambientais, como geotécnicas, e das necessidades das sociedades humanas e apontam-se vias de desenvolvimento futuro que ao autor parecem das mais relevantes.
