天津滨海海相软土成因及物理力学指标分析

Analysis of genesis and physical and mechanical indexes of marine soft soil in Tianjin Binhai New Area

天津滨海新区属海积冲积平原区。浅层海相软土主要由淤泥和淤泥质黏土组成,具有结构疏松、孔隙比大、含水率高和强度低等特点,准确认识其工程性质,深入研究和分析各物理力学参数间相互关系,并建立参数间的相关关系式,建立工程区的经验公式,对工程勘察和设计具有实际应用价值。

Tianjin Binhai New Area is a Marine-alluvial plain.Shallow Marine soft soil is mainly composed of muddy and mucky clay,with the features of loose structure,large void ratio,high moisture content and low strength.Accurate understanding of the engineering properties,further study and analysis of the relationship of the physical and mechanical parameters,and relationship establishment between parameters and have practical application value for engineering investigation and design.
