人工鱼礁群对单桩基础局部冲刷防护效应的试验研究
Experimental study on effect of artificial reefs on local scour protection of monopile foundation
摘要
Abstract
To investigate the influence of artificial reefs on the scour of monopile foundations,a series of physical model experiments on local scour were conducted in a wave-flume.The self-stability of artificial reefs and the protective effects on monopile foundations were analyzed under different wave and flow conditions,types of reefs,layouts,and distances between artificial reefs and monopile foundations.The results show that hollow cubic reefs exhibit better stability than solid reefs.The interlaced arrangement provides superior protec-tion against scour for the monopile foundation compared with the uniform arrangement.Under pure flow con-ditions,the reduction in the scour depth around the monopile foundation due to artificial reefs decreases with the increase of the flow velocity.Under wave and flow conditions,hollow reefs show better effect on the re-duction in the scour depth around the monopile foundation.The different layouts of two types of reefs result in a similar reduction in the scour area around the pile foundation.Changes in the distances between the artificial reefs and the edge of the monopile foundation affect both the depth and morphology of scour.关键词
