摘　　要：软土地基沉降估算的准确性和可靠性,在很大程度上取决于计算参数的准确性.为了合理选取计算参数,在试验工点进行钻探取样、土工试验及多种原位测试手段的综合勘探.通过对不同手段获得的地基土参数的对比分析,提出了较为合理的地基土物理力学设计参数选取方法,对软土地基沉降预测具有一定的参考价值.To a great extent, the veracity and reliability of soft foundation settlement estimation was determined by the veracity of calculating parameters. In order to reasonably selecting calculation parameters, comprehensive explorations were carried out in test points, such as sampling drilling, soil test and several in-situ test means. Through comparative analysis to the foundation soil parameters which obtained by different methods, relatively resonable parameter selecting method was put forward, it has a certain reference value to soft foundation settlement prediction.
