| 摘 要： | 2005年8月7~8日,现代黄河三角洲刁口地区经历了一次由台风麦莎引起的风暴潮过程。通过对比分析风暴潮前后受保护潮坪滩面沉积物的粒度特征变化情况,发现了风暴潮期间在强烈的波浪载荷导致的渗流作用下,粉质土海床出现了极细粉粒由下向上运移并输出滩面的现象。结合现场试验期间采集到的孔隙水压力监测数据,本文基于海床动力响应的观点分析了其成因机制。

| Abstract: | From August 7 to 9,2005,a storm tide took place in Diaokou area of the Yellow River estuary as a result of the typhoon "matsa".During the same period,field observation on the formation of sediment vertical transporting was carried out on tidal flat.Combining the observation result with the analysis of grain-sizes,a conclusion is drawn that some sediments of fine grain size had transported vertically to the tide flat surface under the loading of storm waves,and the exported sediments mainly consists of very fine silty grains.Furthermore,with the data of pore water pressure measured in-situ,an analysis of this phenomemen has been made on the foundation of the theory of sea bed dynamic response to wave loading. |
