中文摘要：

通过先进的潮位和海堤渗压监测仪器及其数据采集系统，获得海堤堤身不同位置实测渗压序列，以及对应的潮位变化曲线，采用序列对比、马氏距离计算、谐量分析方法，对工作在潮位环境下的海堤渗压所具有的一些特殊规律进行分析，归纳总结了渗压与潮位间的关联特点、海堤断面渗压分布规律的多变性以及渗压变化的多周期特征，并对海堤渗压监测模型的建立以及海堤堤身渗压计算提出建议，为有针对性地进行海堤状态的计算、监测、识别提供有效参考。

英文摘要：

We obtained real - time monitoring series of sea wall osmotic pressure at different locations of sea wall and variation curve of correspondent tide level by advanced device and data acquisition system and studied the special rules of sea wall osmotic pressure by series comparison, Mahalanobis metric calculation and harmonic quantity analysis. Through study, the relationship between osmotic pressure and tide level, the polytropy of osmotic pressure distribution rules and multiple periodic rules of osmotic pressure variation are summarized and suggestions on the establishment of the monitoring model for sea wall osmotic pressure and calculation method of sea wall osmotic pressure are put forward as reference for the calculation, monitoring and identification of sea wall state in future studies.
