摘　　要：随着辽东湾浅海油气的开发,该海域海底管道的铺设增多。该区域受潮汐、河流等因素影响,海底管道可能出现裸露与悬跨现象,需要人为定期检测与维护。根据辽东湾海南8管道的检测结果,结合海底沉积物、水文等资料,分析了该海区冲刷机制和现今常用的海底管道裸露与悬跨的维护方法在该海域的适用性。The exploitation of offshore oil in the Liaodong Bay gives rise to the need for massively laying of submarine pipelines.The pipelines may possibly be exposed or even suspended span due to the influences of tides and rivers in the bay,endangering the normal operation of petroleum industry and imperiling the environment.Therefore,the pipelines need to be detected and maintained regularly.Based on the testing results of submarine pipelines in the Hainan 8area in the Liaodong Bay and combining with hydrological data and bottom sediments,the analyses of the scouring mechanism and the applicability of the approaches that have been currently and commonly used for maintaining the exposure and suspended span of the submarine pipelines are made for the area studied.
