{ "description": "<p>The Lower Tagus River Valley area, in Lisbon, Portugal, has been studied for having<br>\na high potential liquefaction risk, due to the geological and geomorphological settings and the<br>\nseismicity associated to the region. This study focuses on the comparison of the cyclic behaviour<br>\nof three sands collected on site, using two distinct laboratory procedures. Tests with different<br>\nvalues of Cyclic Stress Ratio were conducted in both cyclic simple shear and cyclic triaxial testing<br>\napparatus to assess the CRR curves of each material in reconstituted conditions. The comparison<br>\nof the results highlights the main differences caused by distinct cyclic loading stress paths especially<br>\nin view of the results when inversion or rotation of the principal stresses are induced. The<br>\ntests also investigate the influence of the fines content and the cycling frequency in the number<br>\nof cycles required for liquefaction to occur, while discussing the criteria for limit/instability level.</p>", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "creator": [ { "affiliation": "CONSTRUCT-GEO, Faculty of Engineering of University of Porto, Porto, Portugal", "@id": "https://orcid.org/0000-0001-6679-8121", "@type": "Person", "name": "Ramos, Catarina" }, { "affiliation": "CONSTRUCT-GEO, Faculty of Engineering of University of Porto, Porto, Portugal", "@id": "https://orcid.org/0000-0002-9896-1410", "@type": "Person", "name": "Viana da Fonseca, Ant\u00f3nio" }, { "affiliation": "Faculty of Civil and Geodetic Engineering, University of Ljubljana, Ljubljana, Slovenia", "@type": "Person", "name": "Oblak, Ales" }, { "affiliation": "University College London, London, UK", "@type": "Person", "name": "Coop, Matthew" } ], "headline": "Cyclic simple shear and triaxial tests on Lisbon Region liquefiable sands", "image": "https://zenodo.org/static/img/logos/zenodo-gradient-round.svg", "datePublished": "2019-06-17", "url": "https://zenodo.org/record/3465700", "@context": "https://schema.org/", "identifier": "https://doi.org/10.5281/zenodo.3465700", "@id": "https://doi.org/10.5281/zenodo.3465700", "@type": "ScholarlyArticle", "name": "Cyclic simple shear and triaxial tests on Lisbon Region liquefiable sands" }
