真三轴条件下原状黄土的定量化结构性参数研究
Structural quantitative parameter of intact loess based on true tri-axial tests
摘要
Abstract
In order to describe the structural of soil and effect of mechanical caused by its changes,based on the thought of the comprehensive structure potential,combined with the true tri-axial apparatus loading on the intact loess and the disturbed saturated loess with the same dry density,a quantitative comprehensive structural parameter is proposed which can reflect not only the arrangement but also the coherent structure of soil particles,and it is explored the effects of water content,confining pressure and intermediate principal stress on the structural parameter are during the true tri-axial shear process.The results show that the structural parameter is sensitivity,rationality and stability when it reveals the influences of water content,confining pressure and intermediate principal stress on the structure of the intact loess under the true tri-axial shear.关键词
