SPECIFICATION OF ENGINEERING-GEOLOGICAL CONDITIONS OF THE TERRITORY WITH THE HELP OF MICROSEISMS (BY THE EXAMPLE OF SETTLEMENTS OF THE REPUBLIC NORTH OSSETIA-ALANIA)

Abstract

The maps of engineering-geological zonation are the basis for realization of seismic microzonation works (SMZ). The results of engineering investigations allow composing maps of engineering-geological zonation. As a rule, purposeful detail investigations for SMZ of routine urbanized territories are not carried out in recent years because of the absence of necessary financing. For the most part the results of the previous investigations for different kinds of designed buildings and constructions which are spread out in time are used for the problem solving. Microseisms recording technique which allows differentiating areas with different soil conditions quite reliably is offered for usage in the paper. Sections can be detailed with the help of seismic exploration methods if required. The maps of engineering-geological zonation of the cities Vladikavkaz, Beslan, Ardon and Alagir were detailed in a similar way as a result of investigations on the basis of modern geophysical methods.
