| 摘 要： | 辽河油田太—葵管道路由区位于辽东湾顶潮汐水道区。通过不同时期实测水深对比,得出该区海底冲淤变化趋势:海区总体呈微淤态势,潮汐水道两侧浅滩淤积,两侧边坡一侧侵蚀另一侧淤积,发生平面迁移。管道路由一线蚀淤幅度较小,一般不超过0.5 m,最大侵蚀区发生在水道底和两侧边坡,是海底输油管道容易冲刷悬空的潜在危险区,需采取深埋措施提高安全性。

| Abstract: | The Liaohe oilfield Tai-Kui pipeline route area is located in the Liaodong Bay head tidal channel area.The seabed scour and fill trend in the sea area is obtained by comparing the water depth data to each other observed in different periods,and it is shown from the comparison results that the seabed in the area shows a slight siltation trend in general,siltation occurred on the shoal on both sides of tidal channel,one side slope of tidal channel was eroded,and the other side slope was silted.The ranges of erosion and siltation along the pipeline route are small,being no greater than 0.5m in general.The maximum erosion areas occurred on the seabed and the side slopes of tidal channel,and these areas are potentially hazard areas liable to scouring and free spanning of submarine oil pipeline,so it is needed to take a pipeline deep burial measures to enhance the pipeline safety. |
