摘　　要：介绍了在上海某深淤泥港口地基处理中,采用排水板-堆载预压施工方法,根据施工监测资料采用比奥固结非线性有限元法反演地基土的力学参数,以确定能综合反映当时地基状况的参数,并用此参数分析预测场地的后期沉降,为优化施工方案,合理安排工期提供可靠依据。并通过工程实例验证了该方法的可靠性。This article introduces the construction method with the large area pre-loading in the deep slob harbor, according＇to the real observation during construction, the parameters of soil which can reflect the condition of foundation are determined. It offers an upgraded proposal and a reasonable arrangement of the project, that is adopting ＂blot consolidation non-liner finite element method＂ to back analysis of the geological parameters of the foundation and forecast of the ending settlement of the ground. It offers reasonable data for optimizing construction scheme and arranging the schedule of the project. At last, this informational construction is proved to be available through the real cases in the project.
