This paper presents results of the instrumentation of 373 blows from two SPT deployments performed in the Sarapuí II Test Site, located in Duque de Caxias, Rio de Janeiro. In these blows the hammer drop height, its velocity at impact, the rate of blows and also the energy transferred to the rod stem have been measured. It is therefor...
View ArticleLarge-scale mining operations generate vast quantities of tailings that are deposited in hydraulic-fill tailing dams in the form of slurries. Stability of these impoundments require investigation of water table configuration, aquifer boundaries, site characterization and determination of short and long term properties of tailings. These aspects are eval...
View ArticleThis paper deals with the resilient condition that may be reached by driven piles, during its installation as well as under static cyclic and monotonic loading tests. During the 1950’s Van Weele observed its effect in the context of a method for the separation of the toe and shaft loads at failure using the results of static cyclic loading tes...
View ArticleForts, including in this designation military castles, present high complexity due to their nature. Methodologies followed in the rehabilitation of forts are briefly presented, with the emphasis on characterization of materials and rock masses and on tests and numerical models developed for ancient forts. Studies concerning forts with Portuguese legacy ...
