    <description descriptionType="Abstract">&lt;p&gt;The Lower Tagus River Valley area, in Lisbon, Portugal, has been studied for having&lt;br&gt;
a high potential liquefaction risk, due to the geological and geomorphological settings and the&lt;br&gt;
seismicity associated to the region. This study focuses on the comparison of the cyclic behaviour&lt;br&gt;
of three sands collected on site, using two distinct laboratory procedures. Tests with different&lt;br&gt;
values of Cyclic Stress Ratio were conducted in both cyclic simple shear and cyclic triaxial testing&lt;br&gt;
apparatus to assess the CRR curves of each material in reconstituted conditions. The comparison&lt;br&gt;
of the results highlights the main differences caused by distinct cyclic loading stress paths especially&lt;br&gt;
in view of the results when inversion or rotation of the principal stresses are induced. The&lt;br&gt;
tests also investigate the influence of the fines content and the cycling frequency in the number&lt;br&gt;
of cycles required for liquefaction to occur, while discussing the criteria for limit/instability level.&lt;/p&gt;</description>
