an indoor method of artificial structural loess, and studied on the true triaxial tests of artificial
structural loess on the base of improving the original true triaxial apparatus. The results show
that it is reasonably reliable of this artificial method. At the same time, the variation of failure
strength and residual strength of structural loess under complex stress conditions was analysised.
When the confining pressure was less than the structural strength of the structural loess, the
stress-strain curve was soften, on the contrary the stress-strain curve was harden. In the end the
paper analyzed that Mohr-Coulomb strength criterion was accurately to describe the residual
strength variation of structural loess but there has much error in describing the peak broken
strength, the value was obviously small. © (2013) Trans Tech Publications, Switzerland.

Abstract: Macropores resulting from soil pedogenesis and biological activity play important
roles in soil water and chemical transport. Numerous studies have examined individual
macropores and the effects of their size on solute transport, but few have assessed the effects of
