摘要: 从黄土沉积过程和黄土结构分析研究不同压力下黄土的湿陷性。采用室内压缩试验测定黄土的湿陷系数,对黄土试样施加不同的上覆压力,试验方法为单线法和双线法,在上覆压力600 kPa范围内,湿陷系数随压力的增加而增加。

Abstract: The coefficient of collapse of loess on samples were tested under various vertical pressures with both single line and double lines methods. The results indicate that, the coefficient of collapse increases with the vertical pressure. This paper also evaluates the properties of loess from the deposition and microstructures.
