穿越航道的海底管道堆石保护设计方法研究与探讨

穿越航道的海底管道面临着诸多风险,尤其是船舶落锚和拖锚将给其带来严峻的考验。采用的管道保护方法为堆石覆盖保护法。针对堆石保护设计的关键技术,包括堆石层的尺寸设计、管沟边坡稳定性设计、回填石块的粒径级配设计等内容进行了研究和探讨,并就如何进行优化设计提出了一些建议。研究成果在保证管道安全性和经济性方面意义明显,同时还将为今后的工程设计提供一定的理论指导。

Study on Rock Armour Protection Design Method of Subsea Pipeline in Shipping Lanes

The subsea pipeline will be in danger or be damaged under many conditions,especially the severe risk for anchor drop.Rock armour protection method is adopted in this paper.The key technique for rock armour protection design including such contents as dimension of rock berm,trench slope stability,rock grading design and so on are researched,Some suggestions for optimization are presented.The study of this paper has a remarkable means to keep the subsea pipeline safe and economic,and will provide a good theory instruction for engineering design in the future.
