METHOD FOR SELECTION OF MAIN STRUCTURES ROUTE LOCATION IN SEISMIC REGIONS FOR PREVENTION OF DISASTROUS CONSEQUENCES OF EARTHQUAKES

摘要

FIELD: physics, measurement.;SUBSTANCE: invention is related to the field of geophysics and may be used for detection of main structures route. Geophysical and geological survey is carried out in researched territory to identify areas of active fractures on the way of route passage, and main structures are installed. Additionally GPS survey of researched territory is carried out. Lineaments are identified on obtained pictures. Combined chart of identified lineaments is made for this territory. Chart is broken into elementary cells, gradually increasing cells area for analysis of depth structure. Specific length of lineaments is identified in each cell with further making of lineaments specific length field chart. Right-sided and left-sided dynamic shifts are identified. Routes of main structures are placed along with azimuth β₁=α₁-(45°±20°) to left-sided dynamic shift and along with azimuth β₂=α₂+(45°±20°) to right-sided dynamic shift, where β₁ is azimuth of main structure route for left-sided dynamic shift, α₁ is azimuth of left-sided dynamic shift, β₂ is azimuth of main structure route for right-sided dynamic shift, α₂ is azimuth of right-sided dynamic shift.;EFFECT: lower anthropogenic impact at main structures, reduction of disastrous consequences of earthquakes.;2 dwg
