中文摘要：
裸置管线在波浪和潮流等作用下，对海床土强度和整体固结水平产生一定的影响，而产生影响的范围还是一个悬而未决的问题。2005年8月和2006年9月，分别对黄河口地区106钻井平台附近的一条裸置管线以及该地区海床土强度进行了现场微贯测量，结果发现，在该地区水动力作用下，水平方向，管线使得其两侧2m以内海床土强度降低，均匀性变差，尤其是降低了0～40cm深度海床土的强度，并使得其非均匀化程度加剧，使海床土出现成层现象。该研究成果为波浪-管线-土相互作用研究提供了典型实例，并对工程实践提供了借鉴。
英文摘要：
Bare pipelines affect the seabed soil＇s strength and consolidation under wave and tidal actions, while the influence scope is an unsolved problem. In August 2005 and September 2006, there were two insitu measurements in the pipeline affected area, which was near the Shengli Oilfield＇s 106 drilling platform in the Yellow River Estuary, and the pipeline was abandoned and once used to transmit oil. Based on the test results, a series of interesting phenomena were obtained. Under the hydrodynamic force along the hor- izontal direction,the seabed soil＇s strength and uniform became poorer within 2 m distance to the pipeside, and heterogeneity also increased greatly within the 0~40 cm depth range to form stratification. The find- ings provide support to the simulation tests about the soil changes under the pipeline-wave action.
