Uniaxial compression tests for frozen clay were accomplished in test machine with environmental control equipment

which the samples were taken from outside after the clay frozen. Relationship between load and deformation was achieved

compression strength and accordingly deformation were given out

and failure features were observed. The tests show that under the specified test temperature -15 ℃and loading rates range of .5×10-2-1.0×10-5 mm/s; the frozen clay samples have the same features: elastical characteristics shown in first

then some micro cracks born and with the development of micro cracks

macro cracks developed; and samples get to failure at the end. The features shown in our tests are different from that of the remoulded frozen clay.
