PROCEDURE OF SEISMIC MICROZONING Russian patent published in 2001 - IPC

FIELD: structural seismology. SUBSTANCE: invention is intended for evaluation of intensity of seismic vibrations with due account of properties of ground that makes construction site. Seismic vibrations are excited in ground by artificial source, they are recorded by geophones located on sections with different engineering and geological parameters. Magnitudes of actions are determined, peak accelerations and duration of vibrations are measured and weighted mean frequencies of vibration of examined and standard grounds are found as well as increment of magnitude. EFFECT: increased reliability of evaluation and reduced cost of it. 3 tbl
