摘　　要：为了更合理地预测复合地基沉降随时间的变化规律,考虑到灰色Verhulst模型所描述的系统发展S型过程与基础沉降的发生过程一致,引入灰色Verhulst预测模型,以安阳某小区3栋住宅楼施工期间实测沉降数据为基础,计算沉降量与时间关系曲线和最终沉降量。预测结果理想可靠,可以反映全过程的沉降与时间的关系,证明该模型在复合地基沉降预测中具有较好的适用性,可以运用到实际工程中。In order to predict the variation law of composite foundation settlement with time more reasonably,and consider that the system development S shape process described by the grey Verhulst model is consistent with the occurrence process of foundation settlement, the grey Verhulst prediction model is introduced. Based on the settlement data measured during the construction of 3 residential buildings in a residential district in Anyang, the relationship between settlement and time and the final settlement is calculated. The predicted results are ideal and relibale, which can reflect the relationship between settlement and time in the whole process. It is proved the the model has good applicability in predicting the settlement of composite foundation and can be applied to practical engineerings.
