Abstract

The work is devoted to define the seismic hazard degree of four dams of Armenia: Azat, Tavshoot, Haldioom, and Joghaz. The problem required the execution of major geological-geophysical, seismological, tool and theoretical researches. Such studies of the dams in Armenia were carried out for the first time, on the complex of methods designed by us. All research was reduced to a solution of the primary problem, i.e. definition of expected maximum horizontal accelerations (EMHA) of seismic vibrations on the altitude of the investigated dams with compiling of the corresponding epyuras of the distribution of accelerations. For obtaining epyuras the values of EMHA on real, characteristically ground conditions of the territory where the dams are located determined, i.e. holding of seismic microzoning of the investigated territories ground-hydrogeological zones of various seismic hazard with corresponding values of EMHA allocated. As the definition of the marked values of seismic hazard on various ground conditions requires their comparison with the reference value of seismic intensity by particular detailed seismic zoning (DSZ), the research has begun just from operations on detail seismic zoning of regions around the water storage’s.

Definition of Seismic Hazard Degree of Dams and Their Territories, Armenia
