Study of artificial structural loess under true triaxial tests
摘要
Abstract
Structural characteristic is an important basic property of natural loess. The authors have developed an artificial preparation of structural loess, improved the deficiencies of the original true triaxial apparatus and carried out the true triaxial tests of artificial structural loess. The results show that the method of artificial structural loess is reasonably reliable. At the same time, the variation of failure strength and residual strength of structural loess under complex stress conditions is analyzed. When the confining pressure is less than the structural strength of the structural loess soil, the stress-strain curves is softening, and on the contrary hardening. Mohr-Coulomb strength criterion is better to describe the residual strength variation of structural loess and significantly worse to describe the peak breaking strength variation of structural loess.关键词
