海陆交互相下黏性土性状辨析及评价研究

长江口北翼（南通—启东段）沉积物从物性指标判别，物理性质较差，土质分类属于软土或软黏土，而从力学指标判别，力学性质较好，表现出物性与其对应的力学性质指标不完全吻合。分析了出现这种物性“偏软”、力性“偏硬”现象的原因。同时，提出了评价该类土工程特性的新指标，较好地解决了物性与力性不相符合的矛盾。

Evaluation research and distinguishing of cohesive soil properties in the interactive marine & terrestrial deposit

Quaternary period sediment in north side of the Yangtze River estuary (Nantong-Qidong reach) is evaluated by physical property indexes; it has poor properties and belongs to soft soil according to the soil classification system. But evaluated by mechanical properties indexes (a1-2, Es1-2, CPT, SPT etc), the soil has good properties. So it is not all consistent between physical properties indexes and mechanical properties indexes. The phenomenon is analyzed that physical property is poor but mechanical property is good. Now some, new indexes evaluating engineering characteristics of the soil are proposed to solve the inconsistency between physical properties and engineering properties.
