Research on test and analysis for frost damage of base layer of reservoir slope in seasonal permafrost regions

Referenced the fracture mechanics theories, based on the consideration of the destruction characteristics, the cementation force of ice in the frozen soil and fictitious crack, the wing crack fracture model of base layer of reservoir slope is proposed. The calculated results of finite element analysis agree with soil mechanics experimental results in terms of the soil mass of base layer of reservoir slope, which explains this theoretical model and its research methods are reasonable and effective. It is a meaningful attempt to research the anti-frost damage for base layer of reservoir slope in seasonal permafrost regions, and provides a reference for stability design.
