| 摘 要： | 沉降观测是爆炸挤淤筑堤质量检测的一个重要手段，目前其监测方法较多还是按传统的观测法，需要较长的观测时间，耗时耗力。通过分析灰色Verhulst模型的特点，根据实际观测资料运用灰色Verhulst模型预测了堤身各时刻的沉降量，与实际观测具有较好的符合性，并预测了堤身的最终沉降量和所需时间。结合实例预测表明，这一模型具有较好的适用性，可以在类似工程中推广应用。

| Abstract: | Settlement observation is an important method for quality detection in explosive compaction embankment. Nowadays, the traditional observation method is more used; it requires longer time and consumes time and power. By analyzing the characteristics of grey Verhulst model, the embankment settlements of various periods can be predicted according to the observed numbers by applying the Verhulst model. The prediction has good compliance with the actual observation; moreover, the finals settlement and the time it required are predicted. The result shows that the grey Verhulst model is very effective and can be applied to the similar projects. |
