由于在抗拔承载力和深水安装中的优势，拖曳锚在深水系泊系统中具有良好的发展前景。在拖曳锚安装过程中，安装缆绳和锚之间存在复杂的相互作用，安装缆绳在海床土中的反悬链形态将直接影响锚的嵌入和运动，对反悬链形态的研究有助于提高锚的嵌入性能、准确预测锚的运动轨迹以及解决锚在安装中的精确定位问题。基于嵌入缆单元在海床土中的力学模型，推导出适用于黏性土和无黏性土的反悬链方程，利用该方程可求出安装缆绳在海床土中的反悬链形态；通过在缆绳上布置倾角传感器并运用圆弧递推方法，设计出可实时测量嵌入缆形态的试验技术，为验证试验技术的合理性，在空气中分别选取3种典型缆绳形态进行模拟，结果表明：模拟形态与真实形态吻合良好，并具有较高精度；利用实时测量技术开展模型试验，对反悬链方程进行了考察，验证了其模拟嵌入缆反悬链形态的精度，并获取了对拖曳锚安装过程中反悬链形态变化规律的直观认识。

Because of better performances both in pullout capacity and deepwater installation, drag anchors are increasingly applied and play a key role in deepwater mooring systems. During the anchor installation, complicated interaction happens between the anchor and installation line. The penetration and motion of drag anchors are directly affected by the reverse catenary shape of the embedded installation line. Investigating the reverse catenary shape is important for improving the drag embedment performance, precisely predicting the anchor trajectory, and solving the positioning problem of the anchor. In the present work, the reverse catenary equations which can be used to simulate the reverse catenary shape of the embedded installation line both for cohesive and noncohesive soils are derived based on the mechanical model for the embedded line. A technique for real-time measuring the reverse catenary shape based on the tilt transducers and the circular recursive algorithm is also developed. Three typical line profiles are selected to verify the rationality of the experimental technique in the air. The results show high accuracy between the real line profiles and the measured curves by using the technique. The accuracy of the developed equations for simulating the reverse catenary shape of the embedded line is verified by model experiments using the real-time measurement technique. Besides, the model experiments help us to understand the variation of the reverse catenary shape of the embedded anchor line during installation.
