摘要

The purpose of this work is to present a study of the geologic and geotechnical susceptibilityrnof units located in the Figueira da Foz municipality (Central-Western Portugal). A geological and geotechnicalrnsusceptibility classification was established to evaluate rock masses which are constituted by Jurassic and Cretaceousrnrocks (limestones, marls and sandstones). The classification, divided into qualitative and quantitativernparameters and sub-parameters, was applied in 43 outcrops located in the study area. The main parameters arernthe historical record, lithology, geological structures, geomorphology, floods and in situ stress relief. The sumrnof the several parameters varies from 0 to 100. The results can be grouped in classes, from very low to veryrnhigh degree of susceptibility. Two outcrops showed low susceptibility. The majority of the sites scored betweenrn40 and 60 and belong to the medium susceptibility class. The high susceptibility degree is located on costal andrnquarry areas.
