本文系统地介绍了明钢管及埋藏式钢管中的光面管,加劲管和锚筋管的外压稳定计算理论和公式,对各家理论和公式进行了分析、比较和评述,指出了它们的优缺点、存在的问题、其间的联系和区别,并在数量上将它们的计算结果与模型试验和原模观测值进行了比较,向读者推荐了一些较好的公式。本文还试图澄清一些在工程界和学术界存在的有争议的问题。
This paper systematically introduces the calculation theory and formula of the external pressure stability of the smooth tube, stiffened tube and anchor tube in the bright steel tube and the buried steel tube, analyzes and compares the various theories and formulas, and points out that their Advantages and disadvantages, existing problems, the connection and difference between them, and quantitatively compared their calculation results with model tests and original model observations, recommending some good formulas to readers. This article also attempts to clarify some of the controversial issues that exist in engineering and academia.
