软土多种勘察测试成果的相关性分析及应用

Correlation Analysis and Applications of Soft Soil Test Results

珠海横琴岛位于珠江三角洲断陷区南缘,珠江磨刀门出海口的东北侧,场地内沉积了巨厚的淤泥软土。对场址内原位测试、室内土工试验得到的深厚淤泥层的物理力学指标和强度参数进行了相关性分析,得到了该场区软土室内试验、原位测试获得的物理力学指标间的相关关系,并将其应用于工程实践,取得了良好的效果。研究方法和成果对于指导类似软土地区的工程有重要的指导意义。

Hengqin Island of Zhuhai is located in the end of the southern region of the Pearl River Delta Rift,and the northeast side of the Pearl River Modaomen Estuary.The site deposits very thick mucky soft soils.The physical and mechanical properties of the soft soil from the in-situ and laboratory tests are statistically analyzed.The correlations between the physical indices and the mechanical properties are obtained and applied in the project.
