摘　　要：为了建立物理性质与力学性质之间的相关性,通过室内异向固结三轴剪切试验,获得不排水剪强度与上覆土层有效压力的比值Su/p′0,分析Su/p′0与液性指数、塑性指数和液限的相关关系,建立珠三角洲入海口正常固结软土Su/p′0与稠度指标的相关公式,建立归一化特性。In order to establish the correlation between physical properties and mechanical properties, we obtain the ratio of undrained shear strength and effective pressure SJp＇o under the anisotropic consolidation triaxial shear test, analyze the correlation between SJp＇o and liquidity index/plasticity index/liquid limit, and establish the relative formula on normally consolidated soft soil SJpo and consistency index at the estuary of the Pearl river delta, and assess the normalized behavior.

关 键 词：异向固结三轴剪切试验 液性指数 塑性指数 液限 归一化特性
