Abstract
The following paper formulates the criteria of fractured zone size assessment. This article is based on the thesis that the fault zone has to be regarded as a special engineering geologic massif, which is characterized by the stretched form, zonal structure and unfavorable engineering geological conditions. The authors suggest to pay principle attention to the detailed study of the fault structure, composition, sizes and other fault peculiarities. The site of Rogun Hydroelectric Station was reiterated as the object of study. It is situated in the highly complicated rock massif. The site region is characterized by the high activity of modern tectonic movements, and it provides for high strain state of the massif. With the help of boundary element method the questions of the conformity of observable changes in massif—to real width of faults’ dynamic zone, its configuration, the location of stress concentration areas, free surface moving and variation of this parameters during the changes of different conditions were considered. A simulation shows that the zone of stress-strain state changing, received in calculation, is twice a large than it is fixed in nature.
