Conclusions
A method of obtaining a number of indices evaluating the water stabiliby of soil was developed on the basis of ultrasonic sounding.
In addition to the softening ratio and degree of swelling and shrinkage, the comparability of which with the standard indices of the same name is proved by actual data, the possibility of determining the type of weathering and degree (index) of weathering by the new method is also shown.
The prospects of the practical use of the method is related to rejection of labor-intensive laboratory investigations as well as to the possibility of a more broadened engineering-geologic evaluation of soil with respects to its water properties.
