In order to obtain the mechanical properties of pulling force on each layer

this paper establishes cable tension model by finite element method.The geometric model of single core fiber composite submarine cable is established by combining the outer and inner layer shielding and water blocking tape with similar mechanical properties.The model also neglects the outer layer with small thickness and strength.The same structural rigid body ensures the displacement synchronization between the submarine cables.We then simulate the engineering practice of laying and apply the segmented force load to submarine cable.Finally

the mechanical data of stress

strain and plastic strain of submarine cable are obtained.The results show that the stress and strain of each layer structure increase with the increase of stress

and the copper conductor reaches the yield state first.The data provides a reference for the submarine cable laying work.
