土骨架的新概念与沿海软土及海洋土的结构

用土骨架的新概念,对沿海软土及海洋土的结构进行分析。对应我国《建筑地基基础设计规范》GB5007—2011,给出了粉土、粉质黏土、淤泥质土、淤泥、粘土、砂土的土骨架结构形式。结构形式有:粘粒网兜群骨架、粒状联接结构、粒状链结结构、粒状细链结结构、絮状链接结构、开放式粘土基质结构、致密式粘土基质结构、粒状接触结构。

New Concept of Soil Skeleton and Structure of Red Clay

Based on the new concept of soil skeleton,the structure of coastal soft soil and marine soil is analyzed.Corresponding to Code for Design of Building Foundation,GB5007—2011,the soil skeleton structure forms of silty soil,silty clay,silty soil,silt,clay and sandy soil are given.The structure forms are as follows:clay net group skeleton,granular connection structure,granular chain structure,granular fine chain structure,flocculent link structure,open clay matrix structure,compact clay matrix structure,granular contact structure.
