“…A breakthrough of considerable potential importance is the experimental proof that sands may be frozen without discernible effects on their structure, provided that free drainage is permitted away from the freezing front and the effective stress state is maintained during freezing(Yoshimi, et al . , , 1978Walberg, 1978; Singh, et al . , 1979).…”

The Twelfth Joint Meeting of the U.S. -Japan Panel on Wind and Seismic Effects was held in Gaithersburg , Maryland on May 19-23, 1980. The proceedings of the Joint Meeting include the program, the formal resolutions, the Task Committee Reports, and the technical papers. The subjects covered in the papers include:(1) the characterization of seismic ground motion, (2) the characterization of natural wind and extreme wind records, (3) structural response to earthquake loading, (4) storm surge and tsunamis, (5) recent developments in seismic design criteria, ( 6) technical cooperation with developing countries, (7) earthquake hazard mitigation, and ( 8) structural response to wind loading.

A laboratory test program has been conducted to evaluate the 1-D compression and creep properties of intact sand (and silty-sand) samples from a deep borehole at the Malamocco Inlet to the Venice Lagoon. The tests were performed with a CRS consolidometer and include special procedures for trimming the frozen samples, and measuring strains during thawing and backpressure saturation. The specimens have variable fine fractions ranging from 6 to 21% and mica contents ranging from 1 to 10%. The results confirm that there is a strong correlation between

The US Army Corps of Engineers (USACE) completed a liquefaction potential analysis as part of the seismic evaluation of Milford Dam in 1986. This paper uses data from the 1986 study to compare fines content data from in situ frozen and standard penetration test (SPT) samples that suggest fines content can be overestimated by 1-10% by SPT samples in stratified sand deposits. This result may have implications for liquefaction assessments because split-spoon samples may overestimate the actual fines content, resulting in a liquefiable deposit being classified as nonliquefiable. In addition, the paper evaluates the effectiveness of ground freezing on maintaining in situ soil structure and aging of the foundation sands at Milford Dam.Résumé : Le Corps du génie de l'armée américaine (USACE) a réalisé une analyse du potentiel de liquéfaction dans le cadre d'une évaluation sismique du barrage de Milford en 1986. La présente étude utilise les données recueillies lors de l'é-tude de 1986 afin de comparer le contenu en particules fines d'échantillons in situ gelés ainsi que d'échantillons provenant d'essais de pénétration standard (EPS). Ces données suggèrent que le contenu en particules fines peut être surestimé de 1 à 10 % pour les échantillons d'EPS prélevés dans des dépôts de sable stratifié. Ce résultat peut avoir des implications dans l'évaluation de la liquéfaction puisque les échantillons de cuillère fendue peuvent surestimer le contenu en particules fines et ainsi le dépôt liquéfiable est classé comme non-liquéfiable. De plus, cet article évalue l'efficacité de conserver le sol gelé pour maintenir la structure in situ du sol et pour le vieillissement des sables de fondation au barrage de Milford.Mots-clés : mécanique des sols, liquéfaction, résistance au cisaillement, essai de pénétration du cône, essai de pénétration standard, stabilité sismique.[Traduit par la Rédaction]
