摘　　要：本文介绍了计算膨胀节波纹管平面失稳临界压力有关公式，并根据极限分析原理提出了一种平面失稳临界压力计算式。文中同时分析了压力及内压与压缩位移一齐作用时的平面稳定性试验结果。The related formulas to calculate the critical failure pressure of plane stability of expansion joint bellows are introduced, and the calculating formula of critical failure pressure of plane stability is suggested based on limiting analysis principle. The result of test of plane stability is analyzed as well when the expansion joint bellows are subjected to internal pressure and internal pressure together with compression deformation.
