中文摘要：

为充分利用海堤的长期监测资料进行海堤工作状态的判别，着重研究海堤监测中潮位与渗压两个重要监测项目的综合评判。对潮位与渗压实测时间序列分解趋势项，区分时段统计潮位和渗压序列特征值。基于概率论建立海堤潮位与渗压的评判集，根据马氏距离判别海堤状态，建立了对监测样本的状态评判方法。利用某海堤的一组连续实测潮位与渗压序列加以计算判别说明。

英文摘要：

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 impor-tant 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.
