摘要
以某边坡黄土为研究对象,开展固结排水三轴试验,计算结构性参数,分析结构性参数与荷载的关系。研究表明:当应变在0~2%时,结构性参数降低较多,当应变大于2%后,降低幅度变小并趋于稳定,揭示了黄土结构性的变化规律;建立了相关数学方程,可为一定含水量及竖向荷载下的黄土结构性理论及计算提供参考。
Based on the loess of a slope, the consolidated drainage triaxial test was carried out to calculate the structural parameter, and to analyze the relation between the structural parameter and the load. The study results showed that, when the strain was between 0% and 2%, the structural parameter decreased greatly;when the strain was more than 2%, the structural parameter decreased slowly and tended to be stable, which revealed the changing law of the loess structure. Relevant mathematical equations were established, which could provide reference for the theory and calculation of loess structure under certain water content and vertical load.
