Finned piles are considered a novel solution to replace large-diameter piles supporting transmission towers, bridge abutments and so on and are often implemented beneficially for mooring dolphins in offshore areas. This experimental investigation was attempted to examine the lateral response of short-finned piles installed in the proximity of a typical slope of 1V:2H. The 1g model testing of regular and finned piles at different load eccentricities comprised three lateral load tests on horizontal ground and 24 lateral load tests on the slope with the pile at varying distances from the crest. The fin efficiency was observed to decrease with an increase in load eccentricity due to the poorer mobilisation of soil resistance on fins at higher load eccentricities. The finned pile installed at a distance of two pile diameters away from the crest exhibited a net efficiency closer to unity, indicating its ability to improve the receptible subgrade reaction near a loose and steeper sandy slope. An in-depth study of soil resistance developed in the finned pile located at the crest reveals that the fins effectively reduced the soil resistance, specifically in the region above the pivot point.

位于倾斜地面上的横向荷载短翅桩的性能

翅片桩被认为是替代支撑输电塔、桥台等的大直径桩的新颖解决方案，并且通常有利于近海地区的系泊海豚。本实验研究旨在检查安装在 1V:2H 典型坡度附近的短翅桩的横向响应。规则桩和翅片桩在不同荷载偏心距下的1 g模型试验包括水平地面上的 3 次侧向荷载试验和斜坡上的 24 次侧向荷载试验，桩距桩顶的距离不同。据观察，翅片效率随着载荷偏心率的增加而降低，因为在较高的载荷偏心率下翅片上的土壤阻力的调动较差。安装在距离顶部两倍桩直径处的翅片桩表现出接近于统一的净效率，表明其能够改善松散且较陡的沙质斜坡附近的可接受的路基反作用力。对位于顶部的翅片桩产生的土壤阻力的深入研究表明，翅片有效地降低了土壤阻力，特别是在枢轴点上方的区域。
