Title: On the Procedure From Dynamic liquefaction to Seepage Liquefaction of Saturated Sand Soil
Abstract: Based on the liquefaction phenomena observed of saturated sand soil under seismic action and in dynamic test, and from the interaction between water and sand grain, the liquefaction mechanism and procedure of saturated sand under vibrational load were analyzed in this paper. The results from the study show that when saturated sand soil was librated, sand grain will slide and rearrange each other, pore ratio reduce, excess hydrostatic pressure produce and continually increase. At that time, some pore water will be extruded and seepage out. The seepage of the pore water produces seepage pressure on the sinking sand grain. When the sum of the seepage pressure and excess hydrostatic pressure is equal to gravity of sinking sand grain, the sand grain suspends in pore water and the saturated sand soil shows liquid state in macrocosm. The model described the procedure from dynamic liquefaction to seepage liquefaction and liquefaction criterion of saturated sand soil were established.
