Upheaval buckling is a key point in buried pipeline design under high temperature and high pressure conditions. Three analysis methods are discussed in this paper, including analytical method, semi-empirical method and finite element method. The feature and applicability of these methods are summarized for the pipeline upheaval buckling.%海底管线在高温高压条件下的屈曲变形是管线设计中要考虑的一个关键性问题。针对高温高压海底埋设管线，分别采用解析方法、半经验公式法和有限元法进行屈曲分析，并比较不同分析方法的特点和适用性，可为海底埋设管线隆起屈曲分析提供参考。
