摘　　要：黄河三角洲刁口海床分布有大量的输油管线,2005年8月6日至9日台风"麦莎"经过此地形成风暴潮。2005年8月5日和8月12日在风暴潮前后分别对胜利油田106钻井平台附近1条裸置海底管线铺设地区海床土工程性质进行了原位测量,发现(1)由于管线的存在导致管线两侧潮滩的水动力条件发生改变,继而使得两侧海床土的性质发生了变化;(2)风暴潮过后,管线地区海床土强度整体稍有增加。研究结果为波浪与管线共同作用下海床土变化研究提供典型实例。There are massive oil pipelines on the Yellow River Delta seabed,and the existence of the pipelines affected the sea-bed soils strength.The typhoon ＂Matsa＂ passed though this area from August 6th to 9th,2005,and the storm tide was formed.August 5,2005 and August 12,2005,before and after the ＂Matsa＂,there were twice in-situ measurements in the pipeline affected regions,which is near the Shengli Oilfield＇s 106 drilling platform in the Yellow River Estuary,and the pipeline is an abandoned nakedly pipeline which was used to transmit oil.Based on the tests＇ results,a series of interesting phenomena were obtained：（1） Because of the pipeline＇s existence,the pipeline two sides＇ hydrodynamic forces condition changed,and also made seabed soils＇ strength changed;（2） after the storm tide,the sea-bed soils strength and uniformity enhanced.The findings provide support to the simulation tests about the soils＇ changes under the pipeline-wave action.
