泵站建筑物变形面板数据聚类分析方法

Clustering analysis model of deformation panel data for pumping station buildings

  • 摘要: 泵站建筑物监测系统日益完善,监测点数量众多,传统泵站安全监测主要以单测点变形量为主,不能反映泵站建筑物整体的安全性态。以泵站垂直位移为研究对象,基于面板数据聚类理论和动态时间规整算法,建立一种融合趋势信息的泵站变形相似度指标及度量方法,以定量分析测点间监测序列的相似程度;引入空间关联矩阵,提出考虑泵站测点空间关联性的变形分区方法;在此基础上,构建基于面板数据分析方法的泵站变形测点聚类分析模型。结合南水北调某泵站枢纽,验证了模型的有效性。工程实例表明,所构建模型可以根据泵站面板数据将测点分为4个分区,能够有效描述泵站相应区域的总体变形特征和荷载特点,为泵站建筑物安全监测提供了新方法。

     

    Abstract: The monitoring system of pump station buildings becomes increasingly perfect, with a large number of monitoring points. Currently, the monitoring sequence of single point is mainly used in the safety monitoring of pump station building, which cannot reflect the overall state. In view of this, the vertical displacement of pump station was taken as the research object, and a similarity index and corresponding measurement method were put forward to analyze the similarity of monitoring sequences of deformation for pump station quantitatively based on panel data theory and dynamic time warping algorithm. By introducing the spatial incidence matrix, the zoning method of pump station considering the position of measuring points was proposed. Finally, the cluster analysis model of deformation of pump station based on panel data analysis method was established. Then the validity of the proposed model was verified through a case study of a pump station project of the South-to-North Water Diversion Project. The results show the measuring points can be divided into four zones by using the model proposed, and the characteristics of deformation and load are clarified effectively, thus providing a novel method for the safety monitoring of the pump station buildings.
