Title:
SEISMIC BASE ISOLATION BY ELECTRO-OSMOSIS DURING AN EARTHQUAKE EVENT
Document Type and Number:
WIPO Patent Application WO2004022865
Kind Code:
A3
Abstract:
A method and system of isolating a structure (1) and soil mass (2) from earthquake induced vibration by inducing soil liquefaction beneath a structure (1) during an earthquake event, by monitoring local seismic precursor events, such as early arrival ground motion using an accelerometer (4), predicting the onset of a major earthquake tremor and energizing conductors (8, 9) in the ground (2) by a do power source (7) for moving the ground water by electro-osmosis towards a suitable isolation layer (10), whereby raising the pore water pressure in the isolation layer (10) during the earthquake event and thus isolating the structure (1) and soil above the particular soil horizon from the upward propagating shear wave ground motions arising from the earthquake event.
