摘要 基于Tresca、Mises、ASSY、TS 4种屈服准则对完美管道在内压作用下的极限承载力进行推导,得到了完美管道的内压极限承载力理论公式;随后针对内压作用下的周向腐蚀海底管道运用ABAQUS有限元软件进行数值模拟研究,模拟中考虑了材料非线性和几何非线性,并采用0.9倍管材极限抗拉强度作为失效准则,得到周向腐蚀海底管道有限元模拟结果;最后对比采用理论公式与数值模拟结果,可以得出以下结论:当周向腐蚀长度l/Dt(1/2)<12时,数值模拟结果均大于基于ASSY屈服准则进行理论推导得到的公式计算值,当l/Dt(1/2)≥12时,数值模拟结果与基于ASSY屈服准则进行理论推导得到的公式计算值相当吻合,因此工程中可以采用基于ASSY屈服准则的完美管道理论公式对周向腐蚀管道的极限内压承载力进行预测且结果偏于安全。
