摘　　要：基于连续4年的春晓气田群海底管道检测数据,结合该区域水文、气象、泥沙、地形、底质等环境资料的分析研究认为,2007年夏季韦帕、罗莎等台风所引起的强烈水动力扰动,对管道KP287.666～KP301.906所在区域的冲淤稳定产生了较为明显的影响。台风将高能传递给水体,增强了海流、波浪等水动力要素,两者的联合效应使得水体底部剪切应力剧增,使水体挟沙能力加强,对海底造成区域性冲刷,导致管道裸露、悬空,严重影响其安全。Based on a sequence of detection data associating with hydrology,weather,sediment,topography and geology conditions of the area of interest,the authors considered the hydrodynamic disturbance caused by typhoon Wipha and Krosa in 2007 made a significant impact to the scour-and-fill balance in Chunxiao pipeline route between KP287.666 and KP301.906.High wind transfers its energy to seawater,boosts up tide and wave,and then results in a larger bottom stress;furthermore,it strengthens the sediment carrying capacity of flow.These caused regional scour and seriously affected the security of submarine pipeline.
