摘要
在分析埋藏式压力钢管曲屈失稳破坏及其原因的基础上，提出了防止压力钢管曲屈失稳破坏的预防措施．并对国内外现行埋藏式压力钢管抗外压稳定的计算理论和方法进行了分析比较，编制了相应的计算机程序，大大简化了埋藏式压力钢管的抗外压稳定设计．
On basis of the analysis of buckling damage of embedded steel penstocks,some measures preventing steel penstocks from buckling are put forward.Meanwhile,for embedded steel penstocks a comparison among the stability calculating theories and methods used in China and abroad is carried out and a corresponding computer program,which can greatly simplify the stability design of embedded steel penstocks under external pressure,is compiled.
