Three different kinds of artificially frozen soils are tested for artificial ground freezing (AGF) project in
the tunnel construction of Stonecutters Island Sewage Treatment Works, Hong Kong. Uniaxial compressive test is
conducted and uniaxial compressive strength, modulus of elasticity and Poisson’s ratio are obtained. Meanwhile,
relations of all these three parameters and temperature are fitted by linear function. The linear relationship
between the above-mentioned parameters and temperature is suitable for engineering practice. Splitting tensile
test of frozen soil is conducted to obtain tensile strength and find out failure pattern in test. All the parameters
obtained are necessities in design and practice.
