This paper deals with Plaxis 3D finite element simulations of the mechanical response of deep foundations founded in a collapsible tropical soil. Main attention is initially paid to differences between single continuous flight auger (CFA) pile behavior and the behavior of CFA piles in standard groups. The numerically computed load-settlement curves are ...
View ArticleThis paper presents the results of a comprehensive experimental program for investigating the influence of mechanical damage on the load-displacement behavior of geogrids. Unconfined tension tests, pullout and direct shear tests were carried out on intact and damaged specimens. Natural or artificial damages were produced either by imposing heavy compact...
View ArticleThe article consists of the application of a new rating methodology for final disposal of urban solid waste (USW) by evaluating the conformity of geotechnical and environmental aspects during the implementation and operating processes. The IQS was proposed when introducing the concepts of Environmental Management, in accordance with ISO 14001, to the La...
View ArticleThe topographic and geological conditions of several regions in Brazil favour the formation of large deposits of soft soils. Sometimes this requires the use of innovative techniques to allow constructions of geotechnical works in these sites. The presence of deep soft foundation soils has led to an increasing number of reinforced bridge abutments being ...
