摘要

研制一种室内制备人工结构性黄土的方法，在改进原真三轴仪的不足的基础上进行人工制备结构性黄土的真三轴试验研究。结果表明，人工制备结构性黄土的方法合理可靠。同时，分析了结构性黄土在复杂应力条件下的破坏强度及残余强度变化规律，当固结围压小于结构性黄土的结构强度时，土的应力-应变曲线为软化型，反之则为硬化型；Mohr-Coulomb强度准则在描述结构性充分发挥后的残余强度时变化规律较好，在描述峰值破坏强度时则明显偏小，存在较大误差。

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.
