Abstract:Based on the modified unsaturated C.K.C cyclic loader triaxial testing
   system,a series of dynamic triaxial tests were performed on the slurry
   consolidated specimens.The dynamic behavior and deformation
   characteristics of silt clay under traffic loading were studied.The
   effect of drying and wetting on the dynamic strength of saturated silt
   clay was also analyzed.The test results show:the accumulated plastic
   strain of the specimens decreases with the increase of matric suction
   under the same dynamic stress and cyclic loading number;the critical
   dynamic stress and dynamic strength increase with the increase of matric
   suction,however,the dynamic strength growth rate with the increase of
   the matric suction decreases with the increase of matric suction;drying
   and wetting has significant influence on dynamic strength of silt
   clay,the dynamic strength increases after drying and wetting.
