摘要
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 characteristics of silty soil in Shenzhen airport area are the synthetic reflection of its formed environment, substance composition and microstructures.Analysis of the deposition environment of new and old muddy soils is very important for realizing their engineering characteristics,and for consoludating and modifying them for engineering construction. The analysis results show that the new silt soil in marine deposit formed during Q 2 4 inter glacial period and the old one is continental deposit formed during Q 3 3 glacial period Because the engineering characteristics of the two kinds of silt soil are different, so countermeasures should be adopted to deal with the two kinds of muddy soils in engineering construction
