现代河漫滩软土固结与压缩微结构探析

On Microstructural Analysis for Consolidation and Compression of Recent Flood Plain Soft Soil

以长江下游南京市城西曲流段形成的漫滩软土为代表，讨论了现代河漫滩软土的沉积特征、岩土工程性质、物质成分和在固结、压缩作用下微结构的变化，阐述河漫滩相软土的行为，提出了可能的软土地基处理途径。

On the basis of the representative flood plain soil formed at the lower reaches of the curved Yangzi river at the Western Nanjing, the sedimentary features, geotechnical properties, material compositions, and changes of microstructure of soft soil formed by the recent river are discussed. The soft soil behavior is analysed, and a reasonable method to strengthen soft soil foundation is proposed.
