Study on K0 Characteristics of Unsaturated Loess Under Isotropic Stress Path

Loess mainly distributes in arid and semi-arid regions of central and Western China. It is a typical structural soil with special structure and special sensitivity to water. Based on the analysis and summary of previous studies on the mechanical properties of loess, the quantitative and qualitative effects of various factors, especially consolidation conditions, on the mechanical properties of loess are compared and analyzed. The structural change characteristics of loess under isostatic stress ratio compression test were studied. The results show that the strength and deformation characteristics of the soil are not only related to the stress state, but also affected by factors such as the generation mode and the stress path.
