摘要
简述了黄土结构性的损伤演化过程。基于西安理工大学真三轴仪,在真三轴应力路径及增湿等复杂条件下,研究了结构性黄土的结构损伤演化规律;揭示了损伤参数与剪应变、含水率、固结压力、中主应力比之间的关系;通过大量的试验数据,将损伤参数定量化,并将该参数引入应力应变方程,验证了该参数的合理性。
On the basis of the true tri-axial apparatus of Xi＇an University of Technology, in the complex conditions with true tri-axial stress paths and humidity, structural damage of loess and its structural evolution were investigated; the relationships between the damage parameters and shear strain, water content, consolidation pressure, and the principal stress ratio were revealed; through a large number of experimental data, damage parameters were quantized and introduced to stress--strain equation, the reasonableness of the parameters was verified.
