| 摘 要： | 在考虑了环肋圆柱壳在静水压力作用下失稳前周向应力分布不均匀性的基础上，具体提出了其径向变形的近似公式，并由此推导出了总体稳定和局部稳定的理论临界压力公式。实例计算表明其精度提高，同传统的计算公式相比较，物理意义明确，计算结果精确。

| Abstract: | Based upon the consideration of the nonuniformity of circumferential stress distribution ofthe ring - stiffened cylindrical shell under static water pressure before buckling, an approximateformula for calculating the radical deformation is presented and with this formula theoreticalcritical pressure formulae for overall stability and local stability are derived. Example calculationshows that in comparison with the traditional formulae these new formulae afford more accuratecalculation results and clear physical significance. Moreover, the calculation results given arequite accurate. |
