Abstract(s)
Com este estudo pretende-se analisar os xistos alterados, da regiĆ£o de Castelo Branco, como material de aterro no domĆnio das vias de comunicaĆ§Ć£o e barragens de terra.
Este tipo de material, insuficientemente analisado e presente numa vasta Ć”rea de Portugal Continental, apresenta um comportamento caracterizado como evolutivo, no que respeita Ć sua granulometria.
Face ao exposto, Ć© de todo o interesse a determinaĆ§Ć£o das suas propriedades geotĆ©cnicas, numa tentativa de contributo futuro no Ć¢mbito da sua aplicaĆ§Ć£o em obras de Engenharia.
Esta anĆ”lise terĆ” como principal enfoque o estudo das referĆŖncias normativas em vigor, os casos de obras, envolvendo xistos alterados realizados no paĆs e o estudo laboratorial de uma amostra recolhida āin situā e posteriormente ensaiada em laboratĆ³rio.
ABSRACT: With this study is intended to analyze the altered shale, in Castelo Branco region as fill material in the field of communications vias and earth dams. This type of material is unsufficiently analyzed and present in a wide area of Portugal, presents a behavior characterized as evolutive, related to their granulometry. Considering the above mentioned, it is of great interest to determine their geotechnical properties in an attempt to further contribute in its application in engineering works. This analysis will primarily focus in the study of normative references in effect, the cases of works, involving altered schists carried out in the country, and the laboratory study of a sample taken "in situ" and subsequently tested in the laboratory.
