This 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 ArticleA brief background on education and training in Soil Mechanics, Rock Mechanics and Engineering Geology is presented, highlighting some facts which influenced the development of these sciences. The interplay between them is stressed. The International Societies (ISSMGE, ISRM and IAEG) role in promoting education at different levels is emphasised. The per...
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 occurrence of a 5.9 magnitude earthquake, in February 2007, that affected two rockfill dams in Portugal, led to a study presented in this paper about the structural performance of rockfill dams under earthquake influence. Taking into account the world knowledge it can be concluded that the dynamic actions have mainly produced some displacements, and...
