Comparative Study on Triaxial Test of Undisturbed and Remolded Loess

The difference of sample preparation methods will directly lead to the structure sample, and mechanical response characteristics under external load be different. Based on conventional tests such as particle analysis, specific gravity, critical moisture content, consolidation test undisturbed loess from Xi’an, this paper focuses static triaxial consolidated drained shear undrained remolded loess. results show that: (1) has an obvious influence stress-strain relationship curve is a strain softening curve, weak hardening curve; (2) same loading conditions, strength soil significantly higher than that soil; (3) change rule ratio samples basically same, but final greater soil.
