中文摘要：
基于热屈曲理论,考虑独立支撑缺陷对海底管道隆起屈曲的影响,文章推导了独立支撑缺陷海底管道隆起屈曲段长度、隆起屈曲临界荷载和前屈曲荷载,并与已有结果进行了对比,表明：独立支撑缺陷对海底管道隆起屈曲临界荷载有显著的影响,验证了本文研究结果的可行性。
英文摘要：
Based on the theory of thermal buckling, and considering the effect of isolated prop im- perfect geometry on upheaval buckling of subsea pipeline installed on the seabed, critical upheaval buckling length, upheaval critical buckling force and pre-buckling force are derived. The result is compared with the existing results, and shows that isolated prop imperfection has significant effect on upheaval critical buckling force of pipeline, and verifies this paper＇s study feasibility.
