      <title>PORE PRESSURE DEVELOPED IN SATURATED SAND SUBJECTED TO CYCLIC SHEAR STRESS UNDER PARTIAL DRAINAGE CONDITIONS</title>
      <link>https://trid.trb.org/View/276552</link>
      <description><![CDATA[This paper presents the theoretical and experimental studies on the pore pressure developed in saturated sand subjected to cyclic shear stress under partially drained conditions. We analyzed pore pressure buildup obtained under partially drained conditions using the three-dimensional consolidation equation.  Though the rate of pore pressure buildup under undrained conditions has previously been used in this type of analysis (Seed et al, 1976 and Sasaki et al, 1982), the rate used in the present analysis was obtained from a series of cyclic triaxial tests carried out under partially drained conditions.  Specifically, the pore pressure was decreased to a predetermined level of pore pressure which develops in the saturated sand specimen during each single shear stress cycle.  The results of this analysis are useful in estimating the level of pore pressure which can develop, during an earthquake, in saturated sand deposits that have been treated using the gravel drain method. Liquefaction tests on saturated sand under partially drained conditions using the shaking table, were carried out to examine the validity of the analysis.  (TRRL)]]></description>

      <title>EVALUATION OF SOIL LIQUEFACTION POTENTIALS IN PARTIALLY DRAINED CONDITIONS</title>
      <link>https://trid.trb.org/View/276553</link>
      <description><![CDATA[A liquefaction test method has been developed to evaluate liquefaction resistances under partially drained conditions. Both the influence of drainage conditions and the effect of cyclic frequencies on liquefaction are evaluated by conducting several series of liquefaction tests under different conditions of drainage including the undrained condition.  It has been found that the strength increase due to partial drainage can be well represented by the relative density and the coefficient of drainage effect.  A method for evaluating liquefaction potential in partially drained conditions has been proposed and applied to a case study. (TRRL)]]></description>
