俄罗斯伊尔库茨克地区黄土动力特性实验研究

THE LABORATORY STUDY ON DYNAMIC CHARACTERISTICS OF LOESS IN IRKUTSK, RUSSIA

摘要:

利用动三轴实验系统,对俄罗斯伊尔库茨克地区黄土的动力特性进行了研究.获得了该地区黄土的动力特性参数.分析结果表明,该地区黄土的动应力-应变关系符合双曲线模型;动剪模比与剪应变关系曲线具有良好的归一化特性;影响该地区黄土震陷的主要因素是含水量.

Abstract:

The dynamic characteristics of loess in Irkutsk, Russia are studied by using the dynamic triaxial test.The dynamic parameters of the loess are obtained.The results show that the stressstrain relationship obeys the hyperbolic model and the G/G_O~γ_d curves have good normalization character.It is found that the main factor that influences the shock settlement of the loess in Irkutsk is moisture content.
