Abstract: This paper introduces HX-100 Multifunction Triaxial Apparatus,a new type geotechnical laboratory test equipment,and describes an experimental study on the dynamic characteristics of the lateritic soil with this apparatus assisted by Drnevich resonant column,which proves the feasibility of a joint testing with these two kinds of equipment,and finally,by analyzing the test results,reveals some special qualities of the dynamic stres-strain relationship,dynamic shear modulus and damping ratio.
