摘要
建立防波堤沉降预测的非等距灰色Verhulst模型,利用倒数变换对模型的背景值进行优化,提出优化背景值的非等距灰色Verhulst模型的建模步骤。最后结合防波堤工程实例,采用Verhulst模型对其进行沉降预测,结果表明:经过背景值优化的非等距灰色Verhulst模型具有很高的预测精度,适用于防波堤沉降变形预测。
The unequal interval grey verhulst model for the settlement prediction of breakwater is established, which applies the reciprocal transformation to optimize the background value of the grey model,thus the modeling steps of grey verhulst model is proposed,which supports the background value optimization.Finally, the grey verhulst model applies to the settlement prediction of a breakwater project.The results show that the grey verhulst model based on background value optimization has high prediction accuracy and is suitable for the prediction of breakwater settlement and deformation.
