“…To specify the soft boundary conditions (BC) which determine the geostatic state of the considering base fragment, and to modify the BC leading to reconfigure of the stress-strain state of the base, would be the most correct way to set the BC. However, the actual stress state of the rock solid is formed by its weight, tectonic and residual stresses [14] and is usually known only fragmentally and roughly. Formation of the empirical geostatic stress field as a preliminary state is time-consuming and not always possible.…”

The article offers a method, how to estimate the influence of tectonic fault displacements in the foundation of the dam on its stress-strain state, strength and stability. The technique involves analysis of ground-based observation data, processing of radar satellite images and computational research. Diagnostic indicators of neotectonic movements impact are developed with the use of ground-based monitoring data. Small baseline interferometry method is tested as a method of evaluation of recent tectonic activity in the area. The impact, which tectonic fault displacements have on the stress-strain state of a concrete dam, are researched using computational methods. Response of the control equipment in this case is also estimated.
