To make full use of the seawall long-term monitoring data for safety status evaluation,this paper focus on comprehensive evaluation of tidal level and seepage pressure of seawall two important monitoring projects.The trend of tidal level and seepage pressure time series is decomposed.Distinguishing period method is applied to calculate tide and seepage pressure sequence characteristic value.Based on the probability theory,tide and osmotic pressure evaluation set is set up.Based on Mahalanobis distance,evaluation method for monitoring samples is built.A group of continuous measured tide and seepage pressure sequence is calculated and explained.
