摘　　要：针对滨海抽水站沉降情况,提出了基于小波去噪的改进的沉降双曲线预测模型,给出了模型预测方法。采用不同的沉降预测模型通过滨海抽水站沉降观测数据进行沉降预测,结果表明:提出的改进型双曲线预测模型有效地保证了前期预测效果,同时又提高了后期的预测精度,总体效果较其他模型有所改善。An improved hyperbolic settlement prediction model and method based on wavelet denoising is proposed for the settlement of coastal pumping stations. Different settlement prediction models are used to predict the settlement through the settlement observation data of coastal pumping station. The results show that the improved hyperbolic prediction model can effectively guarantee the early prediction effect. At the same time, the prediction accuracy of the later period is improved, and the overall effect is improved compared with other models.
