摘　　要：渤海湾冬季温度低,海冰结冰期长,大型冰块在环境驱动力的驱动下冲击人工岛护坡,危及油田工程和人身的安全,而现有的护坡结构形式很难满足特殊海况的要求,因此提出了一种新型人工岛护坡抗冰结构——伞型块体,并确定了这种新型护坡块体在不同水深下的技术使用参数。模型试验安装与现场应用结果表明,与现有的人工岛护坡结构相比,这种新型抗冰结构形式能够很好地抵抗大型冰块的冲击,经济性显著,具有很好的推广价值。In Bohai Bay, temperature is low and ic- ing period is long in the winter, so that the large ice blocks impact slope of the man-made island due to environmental driving load and endanger oilfield engineering and personal safety, while the exist- ing revetment structure is so difficult to meet this demand under the extra environmental condition. Therefore, a new man-made island revetment andanti-ice structure, namely umbrella block, is put foreword and the technical parameters of the new kind of revetment block are determined for the dif- ferent water depths. Model test installation and field application results have shown that the new type of anti-ice structure can resist the large ice impact effectively, give economic efficiency obvi- ously and have very good promotion value, com- pared with the existing man-made island revet- ment structure.
