摘　　要：随着我国海洋石油工业不断向深水发展,深水柔性管即将获得广泛应用。深水柔性管结构形式复杂,其抗拉层螺旋钢缆在铺管安装和弯曲过程中可能受到轴向压载荷,产生鸟笼现象和侧向屈曲失效,是当前柔性管开发中的研究热点。介绍了国外在柔性管抗拉层钢缆受压载荷失稳的数值模拟和试验研究现状,为我国开展柔性管开发提供参考。Flexible pipes are widely used recently with offshore engineering developing into deepwater or ultra-deep water,especially in China.Flexible pipes are complex structures and tensile armor layers＇ helical wires may result in instabilities in the radial or lateral direction under compressive axial stresses.In this paper,a comprehensive review about recent research on tensile armor buckling behaviors is presented in order to give references to design of flexible pipes in China.
