| 摘 要： | 海底管道冲刷防护是海管研究的热点之一,混凝土联锁排具有整体性好、易于机械化施工等优点在保滩护底工程中得到广泛应用。在易受意外荷载作用的近海冲刷区域,将"混凝土联锁排+土工布"防护型式引入海底管道冲刷防护中,针对裸露或悬空海底管线,探讨混凝土联锁块的防护机理,开展室内水槽试验,选取不同水深工况对比冲刷防护效果并验证了土工布的反滤防护作用,经过分析对比表明"混凝土连锁排+土工布"防护型式适用于海底管线的防护。 |
| 关 键 词： | 混凝土联锁排 海底管线 稳定厚度 冲刷防护 抗浮稳定 |

| Abstract: | Anti-scour protection is one of research focuses for subsea pipeline. There are various protective measures, one of which is the concrete interlocking mattress widely applied in beach bottom protection engineering with the advantage of good integrity and mechanization of construction. In this study, concrete interlocking mattress with geotextile is first applied in subsea pipeline anti-scour protection and its protection mechanism is analyzed. Based on the theoretical analysis, flume experiments were carried out and different scour protection effects for different water depths were compared. Moreover, geotextile filter effect was rerified. It can be concluded that concrete interlocking mattress with geotextile is an efficient protection form for subsea pipelines. |
| Keywords: | concrete slab interlocking mattress subsea pipeline stability thickness anti-scour safety against uplift |
