鱼山海域软土分布特性及其地基处理方法

Soft soil distribution characteristics and ground treatment in the Yushan sea area

为评价鱼山岛海域软土发育特性,进行软弱黏性土层的物理力学性质指标及其空间分布发育特征研究。通过分析其附近海域大量的钻探、十字板剪切试验和土工试验等资料,得知鱼山海域软土主要为夹较多粉砂薄层的淤泥质粉质黏土层,其厚度及埋深均由山前冲洪积地带向滨海地带逐渐变大。同时,提出鱼山地区软土地基处理的方法。

To evaluate the characteristics of soft soil in the Yushan Island sea area,we research the physical and mechanical property indices and spatial distribution development characteristics of soft clay layer based on the analysis of a large number of investigation data from the drilling,vane shear test and geotechnical test data in the sea area near Yushan Island,and conclude that soft soils in the Yushan Island sea area are mainly silty,powdery clay layers interspersed with thin layers of more chalky sand,and its thickness and depth of burial gradually increase from the pre-hill alluvial zone to the coastal zone.Meanwhile,we propose the soft ground treatment method in the Yushan area.
