FIELD: physics.
SUBSTANCE: method for testing frozen ground includes periodic immersion with stopping the probe in the soil mass and measuring the soil resistance to the penetration of the probe and the temperature of the soil. When stopping, after measuring the temperature of the frozen ground, thawing the ground is performed at the predetermined depth with the help of a heating element installed in the probe, after which the probe is pressed within the thawing zone of the soil and the resistance of the thawed ground to the penetration of the probe is measured.
EFFECT: providing the possibility of testing frozen ground with the determination of the mechanical properties and load-bearing capacity of permafrost soils, taking into account their thawing during static probing of soils, increasing the accuracy, reducing the laboriousness of the tests.
