UFRJ-Federal University of Rio de Janeiro and PUC-RJ-Catholic University of Rio de Janeiro, (Brazil) aut Weak rocks in Brazil [Elektronische Daten] [L. Dobereiner] Les roches tendres au Brésil Synopsis: This paper is an outline of the present knowledge of weak rocks in Brazil. The distribution of weak rocks is widespread througout the country. However, the understanding of the engineering behaviour of these materials is still very limited. The site investigation techniques used, are generally standard methods developed for soils or hard rock masses, thus, resulting in poor quality sampling and, in some cases, unreliable test results. Very few large projects have presently been developed in weak rock masses, but in the future, several new sites on those materials will be developed in Brazil.
