PROCEDURE OF SEISMIC MICROZONING Russian patent published in 2001 - IPC

FIELD: structural seismology. SUBSTANCE: invention is meant for evaluation of seismic vibrations with allowance for properties of grounds that compose construction site. Seismic vibrations are excited in ground by artificial source, they are recorded by geophones positioned in sections with various engineering and geological parameters. Angles of slope of ground surfaces of examined and standard grounds bordering on vibration source and located at distance larger than wave of length of seismic vibrations are measured and increment of magnitude is found. EFFECT: enhanced reliability and reduced cost of evaluation procedure. 2 tbl
