【摘要】 针对2011年3月日本9.0级地震,在非震中区域出现砂土液化现象,运用砂土液化机理对砂土液化的判别及处理依据进行了分析,判别6度及以下抗震设防烈度区域其砂土液化等级时,需同时考虑地质环境及地震持续时间的影响,最后对位于海边或内陆河湖边的火力发电厂的砂土液化等级判别及措施提出了建议.更多还原

【Abstract】 Based on the sand liquefaction phenomenon at distant district from epicenter of seismic intensity 9.0 at Japan,Mar.2011,sand liquefaction mechanism is used for analyzing the judgement and treatment basis.When judging the sand liquefaction grade of district with seismic fortification intensity which is no more than 6 degree,influence of geological environment and earthquake duration should be considered.At last,suggestion is provided for sand liquefaction judgment and treatment of thermal power plant which is often located at sea,river and lake side.更多还原
