摘要
近岸海底管线铺设时常常掩埋于海床以下,在长期运行过程中受多种因素干扰而发生裸露,对管线安全运行造成一定威胁。以杭州湾海域册镇海底管线为例,利用多年路由检测资料分析管线掩埋状态发展规律及裸露位置特征,结合海床演变分析发现管线所在海域整体略有冲刷,加上镇海侧围垦工程引起的局部海床冲刷,是管线发生裸露的主要原因。
Due the scour of seabed caused by multiple factors,the exposure and suspension of buried pipelines in coast often happens,threatening the safety of pipelines.In this paper,based on route survey data between 2006-2012 of Cezhen pipeline in the Hangzhou Bay,the buried state of pipeline and the space distribution of exposing pipeline were analysed.In addition,by seabed evolution analysis,the study suggest that the seabed scour in the whole sea and land reclamation near Zhenhai are the main cause of the exposing of pipelines.
