According to the theory of Stokes Law,the test apparatus of flow characteristics of liquefied silt is developed based on the wave test in the numerical wave tank and shaking table test.The apparent viscosity of silty soil is much larger than sand,according to rheological properties tests like dragging ball tests.Wave parameters have great influence on the results,apparent viscosity decreased as wave height increase.Apparent viscosity slowly enlarge with the passing of time at the same wave heights.Along with the increasing of pore pressure ratio,the apparent viscosity of the liquefied silt apparently decreases.This regularity further validate the liquefied silt can be studied as fluid.During the shaking table test,the pore pressure showed a rapid increase,and silt quickly reached a liquefied state; there was consolidation phenomenon in the soil bed,and vibration had a great influence on consolidation; the viscosity values of liquefaction silt was obtained by dragging ball movement,and to analyze the viscosity characteristics.When the soil has not reached completely liquefied state(ru < 1),the apparent viscosity decreases with increasing of excess pore pressure ratio; when it has reached liquefied state(ru = 1),the shear stress decreases with increasing of strain rate.Through the comprehensive analysis of wave tank test and dragging ball test on the vibration table,obtained the following conclusions.In the liquefied state(that is,when effective stress is zero),silt showed shear thinning characteristics that is a typical characteristics non-Newtonian fluid,and using the power law function by fitting the experimental data,we obtained shear stress-shear strain rate relationship formula.
