刘文化, 杨庆, 唐小微, et al. Experimental Study on the Dynamic Characteristics of Unsaturated Soils under Traffic Loading[J]. 2015, 35(2): 263-269. DOI: 10.13409/j.cnki.jdpme.2015.02.020.
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.
