摘　　要：软土地基承载力特征值及变形参数的研究是岩土工程的主要研究内容之一。以营口地区软土为研究对象,论述了该地区软土的工程地质特点,讨论了地基承载力确定的一般方法及影响地基承载力的主要因素;在此基础上,根据静力触探试验和螺旋板载荷试验的结果,结合理论分析建立了承载力特征值与其它指标的相关关系,结合传统理论公式进而建立了营口地区承载力特征值的经验公式。The characteristic value of soft soil foundation＇s bearing capacity and the deformation parameter are ones of the main researching contents in geotechnical engineering. As object with soft soil in Yingkou Area,the paper discusses the features for soft soil geology in present area, the average method for determination of foundation＇ s bearing capacity and the major factors affecting the foundation＇ s bearing capacity. On this basis, in terms of resuits of static cone penetration test and spiral plate load test as well as by theory, it analyzes and establishes the relation of bearing capacity＇ s characteristic value to other targets, moreover around traditional theoretical formula establishes again the empirical formula for bearing capacity＇ s characteristic value in Yingkou Area
