  "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>",
