丽水36-1终端至交付点输气管线工程海床冲刷研究

Study on sea bed erosion of gas transmission line from terminal to delivery point in Lishui 36-1

利用已有大量实测资料对工程海域的水动力泥沙环境及工程海域特别是海底管线路由位置的海床稳定性进行了研究。建立了工程海域考虑波浪作用的二维潮流泥沙数学模型,对考虑周围近期及远期工程建设影响下的滩面冲淤进行了计算,并给出了最终的冲淤分布。

Based on a large number of measured data, seabed stability of project area especially in position of gas transmission line and hydrodynamic and sediment environment were studied in this paper. Then, a mathematical model of tidal flow and sediment was set up to calculate the siltation and erosion of seabed, and the distribution of siltation and erosion was given out.
