摘要
通过对室内试验和各种宏观液化现象中的超孔隙水压力分析发现，孔压比0．6是很有意义的临界值，当孔压比超过0．6以后饱和砂土层就将产生地基失效和隔震作用，并非一定要满足孔压比等于1．0才会产生宏观液化现象。
Value 0.6 of pore pressure ratio is found to be a significant critical value through laboratory tests and various analyses of excess pore-water pressure in macroliquefaction. Ground with saturated sand will lose its bearing capacity and have the function of isolating earthquake as the pore pressure ratio is over 0.6. Macroliquefaction may occur even if pore pressure ratio does not reach to 1.0.
