In article the method of network seismic fields which allows to determine the geoseismic parameters of soil thickness giving seismic characteristic of soil is considered. The average values of speeds of longitudinal and cross waves characterizing the generalized geoseismic section are defined. On the basis of high-speed and density characteristics of soil calculations of increments of seismic intensity concerning parameters of reference soil are executed

Keywords: seismic characteristic of soil, speed of longitudinal waves, speed of cross waves geoseismic section, spatial borders of a geological object
