Compacted Loess Dynamic Characteristics Of The Pilot Study

Based on the west task of ministry of communications and in virtue of GDS dynamic triaxial apparatus, the author does coupling experiments on compacted loess under the different dry density, water content, consolidation stress ratio and consolidation stress. Through careful analyse of tests data, the paper discuss dynamic constitutive relation, dynamic modulus and damping ratio, dynamic deformation and dynamic strength and the relationship between the dynamic behavior of compacted loess with the above different factors. As a result, the paper achieve the basic dynamic behavior of compacted loess within the research scope, which can supply the parameter for the finite element analyses and give the reference to the engineering design and construction.
