%X As a typical spatio-temporal data, the monitoring data of concrete dam deformation in lack at some partial points would bring about inconveniences for deformation analysis. In this paper, we present a method of estimating the missing data of deformation sequence by proposing a spatial proximity point regression interpolation method and a space inverse distance weighted interpolation method based on integral deformation sequences of monitoring points in the vicinity of missing points. Engineering examples verifies that the method proposed in this paper is simple, clear, and is highly precise.
