Es,liq is instead related to a specific value of cyclic<br> resistance ratio or number of cycles at liquefaction via the value of the volumetric component. In<br> fact, for saturated tests (Ev,liq=0) Es,liq is constant for a fixed number of cycles at liquefaction (Nliq).<br> For unsaturated tests, Es,liq increases as Ev,liq increases for a given value of Nliq. The three variables<br> (Ev,liq, Es,liq and Nliq) define a &ldquo;liquefaction surface&rdquo; describing the resistance to liquefaction of<br> unsaturated soils.</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dcat:distribution> <dcat:Distribution> <dct:license rdf:resource="https://creativecommons.org/licenses/by/1.0/legalcode"/> <dcat:accessURL rdf:resource="https://doi.org/10.5281/zenodo.3463558"/> </dcat:Distribution> </dcat:distribution> <dcat:distribution> <dcat:Distribution> <dcat:accessURL>https://doi.org/10.5281/zenodo.3463558</dcat:accessURL> <dcat:byteSize>350766</dcat:byteSize> <dcat:downloadURL>https://zenodo.org/record/3463558/files/Mele et al. 2019 7ICEGE_1.pdf</dcat:downloadURL> <dcat:mediaType>application/pdf</dcat:mediaType> </dcat:Distribution> </dcat:distribution> </rdf:Description> <foaf:Project rdf:about="info:eu-repo/grantAgreement/EC/H2020/700748/"> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">700748</dct:identifier> <dct:title>Assessment and mitigation of liquefaction potential across Europe: a holistic approach to protect structures / infrastructures for improved resilience to earthquake-induced liquefaction disasters</dct:title> <frapo:isAwardedBy> <foaf:Organization> <dct:identifier rdf:datatype="http://www.w3.org/2001/XMLSchema#string">10.13039/501100000780</dct:identifier> <foaf:name>European Commission</foaf:name> </foaf:Organization> </frapo:isAwardedBy> </foaf:Project> </rdf:RDF>
