摘　　要：地基承载力是评价地基的重要参数之一,首先介绍了室内土工试验和原位测试确定地基承载力的方法。结合实际工程采用不同的方法对地基承载力值进行确定。对比不同方法得到的地基承载力值,表明对太湖地区均匀的粉质黏土不同方法确定的地基承载力很接近。对于粉质黏土加粉土层采用静力触探经验公式得到的值与其他方法确定值相差很大,只能给出此土层承载力值的一个大致范围。因此单一的方法无法确定地基承载力值,只有不同的方法相结合才能够较准确的得到地基承载力值。Bearing capacity of foundations is one of the important parameters in the foundation evaluations.In this paper,the calculation methods of bearing capacity of foundation based on the laboratory tests and the in-situ test are introduced.Two methods are utilized to determine the bearing capacity of foundation in a project case history.The magnitude of the bearing capacity of the foundation with different methods are compared and are analyzed.The results indicate that the determining of bearing capacity of foundation with a single method is not accurate.The combination of different methods should be used in order to accurately obtain the value of bearing capacity of the proposed foundations.
