摘　　要：海缆敷设张力的确定是保证敷设工程质量的重要环节,目前对海缆张力的计算很少考虑弯曲刚度的影响。开展不同电缆弯曲刚度对电缆受力影响的水槽模型试验研究。研究结果表明,弯曲刚度对海缆顶部的水平张力影响不大,其主要影响的是海缆水中的姿态。The determination of the tension during the installation of submarine cables is an important aspect of ensuring the quality of the laying process.Currently,the calculation of cable tension rarely takes into account the influence of bending stiffness.This study conducted tank model experiments to investigate the effects of different cable bending stiffness on cable forces.The results indicate that the bending stiffness has little effect on the horizontal tension at the top of the oceanic cable,but primarily affects its orientation in the water.
