Abstract

Abstract

The seafloor sediments in the South China Sea are mainly composed of cohesionless soil with calcareous sand. It is of great significance to study the compression characteristics of cohesionless soil with calcareous sand for engineering safety. Based on the high-pressure triaxial test system, the effects of the calcareous sand content, initial void ratio and effective stress on the compression characteristics of cohesionless soil were studied. The results showed that the increase of the calcareous sand content could improve the compressibility of cohesionless soil under the same effective stress; when the calcareous sand content exceeded 60%, the compression curves of soil specimens in different initial void ratios would converge in the high effective stress region. Based on the above conclusion, a mathematical model was proposed to describe the compression characteristics of cohesionless soil with calcareous sand. The model showed good prediction effect in different sandy soils. Compared with the existing compression model, the superiority of the model was verified.
- calcareous sand,
- cohesionless soil,
- isotropic compression model
