Technique of conducting an experiment to determine the dependence of the strength characteristics of sandy soils on temperature

UDK: 692.115

A.Y. Kolechkina, A.V. Zakharov

The technique of carrying out the experiment to determine the dependence of the strength characteristics of sandy soils on temperature is considered in the article. The physical characteristics of the investigated soil are determined - moisture, particle size distribution and particle density. The boundary conditions of humidity for soil samples were found. Strength characteristics of the soil were determined with the help of ASIS systems. The sequence of sample formation is considered - setting the sample to moisture, sealing it, forming, cooling and testing in a single-plane cutter. Cooling was carried out to temperatures of t2 ° C and 12 ° C, the remaining samples were tested at room temperature (about 22 ° C). The article contains illustrations with a sequence of carrying out this experiment. In the course of the experiment, the temperature of the samples was measured two times - before testing in a single-plane cutter and after. All the obtained values ​​of the specific cohesion, the angle of internal friction and temperature are tabulated.
