Abstract

Based on the 2-D tide current numerical simulation, the seabed evolution calculations with tide current and the seabed evolution calculations under the interaction of waves and tide currents, the case tests mainly study tide flow velocity distribution characteristic, flow pattern variety and seabed evolution on the pipeline and nearby sea area before or after the project near the LNG pipeline is built. After all kinds of sea embankment projects are brought to effect, by comparing and analysing the calculation results of tide flow velocity, erosion depth and erosion range, do the evaluation of schemes of sea embankment project, and provide scientific basis for decision-making department to choose the sea embankment scheme.

Keywords: Numerical simulation, pipeline, embankment project, seabed evolution
