摘要：

为了研究外压作用下深海腐蚀缺陷管道的屈曲失稳机理，通过深海压力舱小比例模型试验，测得钢管试件发生屈曲失稳时的压力和变形形态. 利用有限元软件ABAQUS建立管道的三维数值模型，模拟外压作用下完好无损管道和腐蚀缺陷管道的准静态屈曲失稳过程，得到钢管的压力-直径变化曲线和变形形态，与试验结果吻合良好. 采用建立的数值模拟方法，分析管道长度、径厚比、初始椭圆率、钢材等级、钢材应变硬化特性和缺陷几何尺寸等因素对腐蚀缺陷管道屈曲失稳的影响. 结果表明，初始椭圆率、缺陷几何尺寸、钢材应变硬化特性是深海腐蚀缺陷管道标准化后失稳压力的主要影响因素，管道长度、径厚比、钢材等级对标准化后失稳压力的影响相对较小.

Abstract:

The small-scale model experiments for steel tube specimens were conducted in a deep-sea hyperbaric chamber to measure the pressure and deformation configurations when the buckle and collapse occurred in order to analyze the buckle and collapse mechanisms of deep-sea corrosion defect pipes under external pressure. A three-dimensional numerical model of the pipe was established using the finite element software ABAQUS to simulate the quasi-static collapsing process of intact and corrosion defect pipes under external pressure. The pressure-change in diameter response curves and deformation configurations of steel pipes accorded well with the experimental results. The effects of pipe length, diameter-to-thickness ratio, initial ovality, steel grade, strain hardening characteristic of steel and geometric size of defects on the buckle and collapse of corrosion defect pipes were analyzed by using the developed numerical simulation method. Results show that initial ovality, geometric size of defects, and strain hardening characteristic of steel are the major factors affecting the normalized collapse pressure of deep-sea corrosion defect pipes, while the effects of pipe length, diameter-to-thickness ratio, and steel grade on the normalized collapse pressure are comparatively small.
