Cone penetration in mixed or intermediate soils (soils containing mixtures of sand, silt and clay) is neither fully drained nor fully undrained at the standard cone penetration rate of 20 mm/s. Considerable research, mainly relying on centrifuge tests, has been undertaken to quantify the effects of penetration rate (and thus partial drainage) on cone re...
View ArticleThis 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 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 ...
View ArticleFor an appropriate stability analysis of pre-treated MSW landfill, the shear strength parameters of the material should be well defined in order to have a more realistic assessment of its geomechanical behaviour. As is well known, the shear strength of the material can be determined using two distinct components: friction (between the granular particles...
