In conclusion, it will follow that recently there has been a desire to introduce a dynamic test of soil into practice. A number of specially designed devices appeared in Germany, allowing a concussion of soil with the desired frequency and the desired intensity. All devices operating with a small area do not bring great benefits, as it is well known, the influence of the area on the value of precipitation. In our Union, the first attempts to test the soils were made by VIOS using the vibrational machine of the Losenhausen system, installed on a special experimental foundation with sizes in the plan of 3.5 x 2.5 m and a height of 1.0 m. The weight of the car in a calm state is 8.25 g.
