The Influence of Tectonic Faults on a Stress-Strain State of a Large Concrete Dam

Abstract:

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.
