Research status of dynamic properties of artificial frozen soil and its significance

Based on the data of artificial frozen soil and polycrystalline ice in uniaxial creep tests and the result of structure duplication electronmicroscope, this paper discussed the microstructure damage behaviour and change characteristic of frozen soil in the creep process.

Cold end temperature-changing experimental research on the artificially frozen soil;

Numerical calculation of creep displacement of artificially frozen soil under combined stresses;

The small-strain stiffness characteristic of artificially frozen soil in deep alluvium was investigated at different initial confining pressures and frozen temperatures by secant Young’s modulus representing the soil stiffness.

Exploring artificial freezing soil s speciality of frost-heaving and thaw-settlement is keytechnology and important basal research about popularizing artificial freezing method for municipal underground space.

The Liuzhuang coal mine of Huainan,whose primary well tower adopts artificial frost-thawed soil as foundation,but in the course of freezing and thawing,the thermal regime of artificial frost-thawed soil have changes a lot.
