BARRIER TO PROTECT DEVELOPED AREAS AGAINST SURFACE SEISMIC WAVES Russian patent published in 2013 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: barrier against protection of developed areas against surface seismic waves surrounds a protected area, the upper edge of which is at the level with the soil surface. The barrier in plan is arranged as convex, the barrier depth is arranged as at least 0.2 of the wave length, the width of the barrier wall - at least as one length of the wave. The wave length is accepted as corresponding to the lowest frequency of the most dangerous frequencies of oscillations for this region, determined by spectra of earthquake accelerograms. The distance between borders of structures and the inner border of the barrier makes at least 0.35 of the barrier width, and the barrier material is performed with density of at least twice higher than density of the surrounding soil.

EFFECT: higher efficiency of territory protection against seismic waves.
