A large planar landslide on a slope between the Bridge 25 the Abril and Trafaria (Almada)
Resumo
This paper describes the mechanism that has triggered a large planar landslide which occurred in the segment of the slopes between the “25 de Abril” bridge and the village of Trafaria, in Almada County.
The geological and geomorphologic conditions at the site have imported to this landslide some characteristics that are different from those related to other landslides that have occurred in this zone. Along with this back analysis study, the most relevant morphological and geotechnical features involved are briefly dealt with in the paper.
Neste trabalho descreve-se o mecanismo que desencadeou um escorregamento planar de extensão importante, ocorrido no trecho de taludes entre a Ponte 25 de Abril e Trafaria, no Concelho de Almada, e as condições geológicas e geomorfológicas que induziram características distintas das de outros escorregamentos também ocorrentes naquele trecho de taludes.
No estudo por retroanálise do mecanismo de rotura abordam-se, sucintamente, os factores morfológicos e geotécnicos considerados mais relevantes.
