Being the manner which at the time of the exemption shaking null earthquake event

摘要

Solutions Using the accelerometer, vis-a-vis the shear wave ground movement which to upward you watch the omen phenomenon of the local earthquake early like arrival ground movement, estimate the startup of the ground vibration, you turn on electricity to the conductor in ground with direct voltage source and facing to appropriate exemption shaking layer, you move the underground water due to electroendosmose, you rise the pore water pressure of this exemption shaking inside layer with this, causes the soil liquefied conversion to which exemption shaking layer of specification is localized with that selectively at the time of earthquake phenomenon, it occurs from earthquake phenomenon with that is spread the structure of the upper part of the soil stratum of that specificationMethod and the system which designate the structure vis-a-vis the vibration which is pulled up in the earthquake due to under the truth of the structure causing soil liquefied conversion at the time of earthquake phenomenon and by designating the soil as exemption shaking, and the soil lump as exemption shaking.
