深圳机场淤泥土的工程特性是其形成环境、物质组成及微观结构特征的综合反映，该区分布的新老两层淤泥沉积环境分析，对认识其工程特性及其本质，对其加固改良应用于工程实践有着十分重要的作用。研究表明， 机场区新淤泥是Ｑ２４ 间冰期的海相沉积， 而老淤泥则是Ｑ３３ 冰期的陆相河湖沉积。二者工程特性有较大的差异， 在工程建设中应区别对待， 采取不同的工程措施。
The engineering properties of the silt in Shenzhen Airport are the comprehensive reflection of its forming environment, material composition and microstructure characteristics. The analysis of the sediment environment of old and new silos distributed in this area is of great help to understand its engineering characteristics and its essence, Engineering practice has a very important role. The research shows that the new silt in the airport area is the marine sediment during the Q24 glacial period, while the old silt is the continental lacustrine sediment in the Q33 glacial period. The two engineering characteristics have greater differences in the construction should be treated differently, to take different engineering measures.
