摘要
介绍了海底光缆面临的锚害现状,针对现有抛锚贯入深度计算方法的不足,提出用有限元法模拟抛锚贯入深度的方法,即利用ABAQUS软件建立抛锚贯入深度数值分析仿真模型。通过此方法分析了锚自身尺寸与质量、落锚速度及海底土壤不排水抗剪强度对船锚贯入深度的影响,并以具体的数值呈现出来。这对海底光缆的抗锚害设计具有一定的理论指导意义。
The anchor damage status which the submarine fiber optic cable faced with is introduced.Aiming at the drawbacks of the existing calculation method for anchoring penetration depth,a method of using finite element method to simulate anchoring penetration depth is proposed,that is using ABAQUS software to establish numerical analysis simulate model of anchoring penetration depth.The influences of the size,mass and dropping speed of the anchor and the undrained shear strength of the submarine soil on the anchoring penetration depth are analyzed,and shown in specific numerical values.This has a certain theoretical guiding significance for the design of anti anchor damage of submarine fiber optic cable.
