Plate anchors are among the most effective anchorage systems that are widely used to resist horizontal and inclined uplift loads in many offshore and onshore applications. Previous research on plate anchors has largely focused on the horizontal or vertical breakout problems, with limited attention directed towards obtaining a full characterization of the effects of anchor orientation angle. The present study utilizes displacement-based finite element analyses to investigate the stability and performance of strip anchor embedded in cohesionless soil for plate inclination angles ranging from 0° to 90° from horizontal, where the applied load is normal to and acts at the center of the plate. This study investigates the effects of scale and roughness, along with the geometry of the failure mechanism for various plate orientations and embedment depths. The analyses, presented in terms of a non-dimensional breakout factor Nq, show that the breakout factor increases significantly with an increase in the inclination, especially for angles greater than 45° in loose sand and greater than 60° in dense sand. The analyses also show that scale effects (anchor width) can affect capacity. Finite element analyses have been used to introduce simple design charts relating the breakout factor to the embedment depth and relative density. Comparisons to experimental and numerical studies showed good agreement.

板锚是最有效的锚固系统之一，在许多海上和陆上应用中广泛用于抵抗水平和倾斜的抬升载荷。以前对板锚的研究主要集中在水平或垂直突破问题上，很少关注获得锚定向角影响的完整表征。本研究利用基于位移的有限元分析来研究嵌入无粘性土壤中的条形锚的稳定性和性能，板倾斜角度范围为 0° 到 90° 与水平面，其中施加的载荷垂直于并作用于中心碟子。这项研究调查了尺度和粗糙度的影响，以及各种板取向和嵌入深度的失效机制的几何形状。以无量纲爆破因子 Nq 表示的分析表明，爆破因子随着倾角的增加而显着增加，尤其是对于松散沙土中大于 45° 的角度和密沙中大于 60° 的角度。分析还表明，规模效应（锚宽度）会影响容量。有限元分析已被用于介绍将突破系数与嵌入深度和相对密度相关联的简单设计图表。与实验和数值研究的比较显示出良好的一致性。分析还表明，规模效应（锚宽度）会影响容量。有限元分析已被用于介绍将突破系数与嵌入深度和相对密度相关联的简单设计图表。与实验和数值研究的比较显示出良好的一致性。分析还表明，规模效应（锚宽度）会影响容量。有限元分析已被用于介绍将突破系数与嵌入深度和相对密度相关联的简单设计图表。与实验和数值研究的比较显示出良好的一致性。
