摘　　要：本文在原有土体固结增强理论的基础上,考虑不同固结度下土体强度指标的增加,提出了改进后的土体固结增强模型。通过纳米比亚某项目筑岛前后的数据对比表明该改进模型能够很好的反应硅藻土质粉土地基土的强度增长规律。Based on the soil mass consolidation theory, an improved model for simulating soil mass consolidation has been proposed by considering the increase of soil strength index under different degrees of consolidation. The improved model can reflect well the strength growth law of diatomite silty foundation according to the comparative analysis of soil mass strength data before and after the island development project in Namibia.
