| 摘 要： | 运用灰色理论建立地基沉降的非等时距的等维新息预测模型。采用胶州湾底海岸吹填区的地面沉降监测数据对预测模型进行检验,并与普通GM(1,1)模型的模拟结果进行比较,该模型的预测精度和计算精度均高于普通GM(1,1)模型,预测数据与实测数据的误差较小。本研究成果对类似的吹填区软土地基沉降监测具有一定参考价值。

| Abstract: | Based on Grey Theory, a unequal interval, equal dimensional innovation prediction model is established for foundation settlement. The prediction model is tested by ground settlement monitoring data of coastal dredger-fill zone in Jiaozhou Bay, and compared with normal GM （1, 1） model. It is shown that the proposed model is of higher prediction and calculation accuracies than normal GM （1, 1 ） model, and there are a few differences between the predicted and measured data. The research result will provide the reference for monitoring settlement of soft deposits formed by similar dredger fills. |
