The Mechanical Properties And The Structure Of The Deep Frozen Clay

This article main content includes:the deep research of artificial frozen soil mechanics experiment, respectively through the permafrost of the uniaxial compressive strength experiments to determine the load, temperature, localized, curing time, time effect factors such as the relationship between the compressive strength of frozen soil, and analyzed the reshaping of permafrost and the characteristics of the undisturbed frozen soil strength and failure strain; Through frozen soil compression creep test, the creep constitutive model, the modified d rove constitutive model, and the constitutive parameters through experiments. For structural clay, respectively from the clay particle breakage, slip and rheological properties, etc, to analyze the structure characteristic of the clay, the structural model provides a theoretical basis for establishing a clay. And stress theory to establish the structural elastic-viscous plastic constitutive model of soil, respectively to obtain the yield function and damage of structural damage function and hardening law and damage law, as well as to the damage plasticity coefficient is calculated and the determination of model parameters. To draw a deep frozen clay structure characteristic and the factors affecting the mechanical properties of artificial frozen clay.
