| 摘 要： | 这里介绍一种受外部压力作用的压力容器，这种容器可为海下采油提供一个大气压力的空间．该种容器的外壁是由内外两层钢皮内浇注混凝土而成的＂Ｓａｎｄｗｉｃｈ＂结构．本文对其受力性能用分层有限元法进行了计算，并将结果同英国曼彻斯特大学的实验数据进行了对比，吻合较好，初步验证了作者所编程序的可行性，并得出一些结论．

| Abstract: | A new kind of vessel existing external pressure is introduce in this paper.The vessel can provide one-atmosphere space for developing sub-sea oil.If the end effects are neglected,it looks like a infinite long cylindric shell.Its walls are composed of two thin steel skins with concrete filled between them.Its properties under the external pressure have been calculated with the layer method and 8-nodes FEM and the results have been compared with the Manchester University's experiment data. The agreement shows that the computer program is feasible.Finally,several condusions are drawn. |
