Resumen
SANDOVAL VALLEJO, EIMAR. LIQUEFACTION RESISTANCE OF CALCAREOUS SANDS. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.173, pp.32-40. ISSN 0012-7353.
Calcareous sands are unique in terms of their origin, mineralogy, shape, fragility and intraparticle porosity. This article presents results from an experimental program carried out to study the liquefaction resistance of a calcareous sand retrieved from Cabo Rojo at Puerto Rico. The experimental program included mineralogical characterization, index properties, and undrained cyclic triaxial tests on isotropically consolidated reconstituted samples. Due to the large variation in the calcareous sand properties, results are compared with previous researches carried out on other calcareous sands around the world. Results showed a wide range in the liquefaction resistance of the studied calcareous sands. Cabo Rojo sand experienced greater liquefaction resistance than most of the calcareous sands used for comparison. Important differences in the excess pore pressure generation characteristics were also found.
