昆明盆地浅层软土因含水率极高、孔隙比极大、压缩性极高等特性而有别于上海、福州等沿海地区的软土,通过搜集昆明市南市区27个软土场地的土工试验结果,对比分析其参数,得出内聚力与各物理指标之间的单一线性关系和多元线性关系的回归系数均过低,预示着软土内聚力与有机质含量密切相关.在以后的工程建设中,需考虑分析有机质含量与内聚力的关系,为工程设计提供更为准确的设计参数.%The soft soil in the south city, Kunming, Yunnan Province was different with the soft soil in the coastal areas because of its high moisture content, void ratio, compressibility. Twenty seven areas, which are constituted by soft soil, in the south city, Kunming, Yunnan Province have been studied in order to get the correlativity between the cohesion and physical parameter. The result shows that neither the liner relation nor the multivariate linear relation was too low to put forward a empirical formula between them, which indicate the cohesion might be closely related to the organic content. The relationship between the organic matter content and the cohesion should be considered in the later project construction, in order to provide more accurate design parameters for the engineering design.
