Análise de problemas de geologia de engenharia em zonas diapíricas: os casos de Belo Horizonte, Santa Clara e Morro do Lena (Leiria)

Belo Horizonte, Santa Clara and Morro do Lena are new areas of urban expansion of Leiria town. Geologically, these areas are located in a diapiric structure, Leiria-Parceiros, characterized by a great geological diversity. The main goal of this research is to stress out the critical aspects not only about geology but essentially to emphasize the consequences of such a complex structure like a diapir on the implementation of engineering structures. The work identifies and analyses the main problematic aspects, in an integrated way, the geomechanical properties of rocks and soils as well as some technical restrictions to be made in the type of foundation in diapiric areas.
