Abstract

The variation regularity of submarine pipeline's status in Hangzhou Bay was analyzed based on inspecting data over years. The variational reasons of pipeline's exposed and buried status were explored based on the hydrodynamic numerical model and the integrated factors such as the self-burying design of Spoiler, the flow characteristics and the seabed evolution, the human activities in Hangzhou Bay and so on. The results show that above 80% of the pipelines are buried under seabed,while some parts of pipeline are chronically unburied, and the unburied pipelines are mainly located in the deep groove of north shore and the frontier of Andong Beach. The pipeline's scouring is close related to the seabed variational characteristics, the angle between the flow and pipeline, and the self-burying design of Spoiler. In addition, the reclamation project in the south beach of Hangzhou Bay may play an important rule for the pipeline's exposed and buried status.
