For the first time opportunity of use of acoustic fluctuations theoretically is reasonable as the carrier of the information about his intense-deformed condition, that enables to estimate a site and character of abnormal zones in a district of development. The methods of laboratory and mathematical modeling establish the basic parameters anchor support, dependent from the sizes abnormal zones formed around of development after its realization.
