深圳机场三跑道扩建工程软土特性研究
|
摘要
在分析珠江口伶仃洋海域附近水域滩槽演变及泥沙特性的基础上,对项目所在区域的岩土地层及其特点进行了总结分析,主要的软土层为浅部淤泥、淤泥质土夹粉砂层和深部淤泥质土层,沿层理面夹有薄层粉细砂或中粗砂,垂直向上厚度变化极不均匀。并对这三类软土的物理力学特征指标进行深入研究,揭示其工程特性,为项目后续软基处理提供基础资料。
After the analysis of trough evolution and sediment characteristics in waters near the Pearl River Estuary in the Lingding Ocean,classify the soil stratigraghy and analyze the characteristics of the strata. The main soft soil is shallow silt and silt soil with silty sand and deep silty soil,with a thin layer of fine sand or sand along the bedding plane,vertical thickness is uneven. The physical and mechanical properties and engineering characteristics of the three kinds of soft soil are studied,which provides basic data for the subsequent soft foundation treatment of the project.
