Detailed Seismological Studies the Junction of Different landscapes in South Yakutia

Research objective - determination of the quantitative indicators of seismic wave attenuation on the area of geotechnical landscapes with contrasting properties and the forecast of the seismic intensity impact within the area of study of the linear engineering structure in conditions of permafrost zone. During the research tasks were performed: study of the geotechnical structure of the area, registration of the microseismic disturbance, acceleration graph of the industrial explosions and powerful man-caused sources of the seismic waves. Main hypothesis of the study - contrast saving of the seismic properties of for-mation from geotechnical landscapes of rooted slopes and above floodplain river terrac-es in conditions of the permafrost zone. During the research complex of geophysical and seismological researches was performed, drawing of the geotechnical section confirmed by the drilling data. Results of the study confirmed main hypothesis - major difference of seismic properties of frost soils foundations for joint landscapes has been established.
