Abstract

The deformation of concrete gravity dams can directly reflect the comprehensive operational state of dams, and the deformation monitoring data is the direct reflection of the dam deformation. Therefore, it is of great significance to grasp the rules and correlation between the dam deformation monitoring data in time and space for the subsequent research on anomaly detection and safety evaluation of dams. Combining with the deformation monitoring data examples, the lag in the effect of environmental factors on displacement is analyzed. Using the spatio-temporal similarity index, the comprehensive similarity index is constructed for the displacements between different monitoring points of the dam. The correlation between the displacement of different monitoring points and the correlation between environmental factors and displacement of monitoring points are analyzed by using Pearson’s correlation coefficient method, Spearman’s correlation coefficient method and Maximum Information Coefficient method. It lays a solid foundation for the subsequent research such as the establishment of healthy service diagnostic models.
