中文摘要：

从近代海相地貌特征分析了江苏海相软土的形成。通过室内外试验数据的分析研究发现，该海相软土属于高含水专、高压缩性、高孔隙比、高液限、低承载力的淤泥质海相灵敏性软土。根据工程实践提出了有关海相软土加固处理的设计方法、施工技术的建议。

英文摘要：

The deposit features of Jiangsu marine soft soils was investigated based on Holocene epoch marine geomophology characteristics; the sediment history of Jiangsu marine soft soils is about 6000 years. The depth of embedment and thickness of soil layer of Jiangsu marine soft soils are of fluctuant varying because of effect of many times of transgressions and regressions. Through analysis and research of laboratory and field test data, Jiangsu marine soft soils are of features of high water content, high compression, high void ratio, high liquid limit, low bearing capacity and sensitive warp clay. Otherwise, we present some suggestion for ground improvement methods of design and construction.
