Abstract

A evolução morfológica do trecho setentrional da arriba fóssil da Costa de Caparica, compreendido entre S. Pedro da Trafaria e a via rápida IC20, tem-se vindo a notar nas últimas décadas, sendo devida, em grande medida, à crescente interferência das actividades antrópicas nas suas proximidades. Neste trabalho, após breve caracterização geomorfológica e geotécnica daquele trecho de escarpas, discutem-se alguns mecanismos de rotura a partir de retro análise baseada nas evidências morfológicas deixadas por dois desmoronamentos, considerados típicos, naquele local.

The morphological evolution of the northern part of the "Costa de Caparica fossil cliff",between S. Pedro de Trafaria and the IC 20 highway, has been quite notorious during the last few decades andit is related mainly to the increase of human activities in the neighboring areas.The geomorphologic and geotechnical properties of the cliff materials are presented in this paper and thefailure mechanisms of two typical rock fall occurrences are discussed, after some back analysis calculations.
