中文摘要:
      滑坡发生前伴随着不同程度的变形发生,变形监测与安全监控问题相应地引起各级政府和管理部门越来越多的关注。本文研究了滑坡深部位移的监测数据异常值检验方法和含噪数据的消噪方法,并在此基础上,研究小波分析与时间序列分析结合的数据预报方法。通过具体实例表明:小波对监测信号消噪可以得到有用信息,能够提高模型稳定性和可靠性;小波时间序列模型对滑坡安全监测数据进行预测,精度能够满足安全监测要求。

      Before the occurrence of landslides associated with different degrees of deformation occurred,deformation monitoring and safety monitoring issues have got more and more attention of management departments and government.This paper based on wavelet theory to research the abnormal deformation value testing and noise reduction method.Also it is significant to research the forecasting method,which combines wavelet analysis with time series modeling.Through concrete examples,Wavelet De-noising of monitoring can ...
