砂土中拖曳锚安装特性试验研究
Experimental study on characteristics of drag anchor installation in sand
摘要
Abstract
To investigate the installation mechanism of drag anchors in sand and the influencing factors,an ex-perimental study on the drag anchor installation in sand is conducted using a self-developed testing set-up.The effects of the dragging speed,the configuration of the shank,and the relative density of sand on the installa-tion behavior and holding capacity of drag anchors are systematically explored.The experimental results dem-onstrate that excessively high dragging speed can accelerate the development of roll angle and increase the risk of installation failure due to roll-out.A smaller anchor shank helps to increase the ultimate embedment depth and the holding capacity of the drag anchor.The ultimate holding capacities of the single shank anchor in me-dium dense sand and loose sand are about 2.06 and 2.28 times that of the Mk6 anchor.The higher the relative density of sand,the lower the ultimate penetration depth achievable during installation and the lower the hold-ing capacity.The ultimate bearing capacities of the Mk6 anchor and the single shank anchor in loose sand in-crease by 60%and 76%compared to that in medium dense sand.关键词
