本文运用双矩弱作用屈服条件，分析了密集补强型球壳开孔接管的五类九种破坏机构的完全解，并给出了各类机构所适用的参数范围；从而为建立一种开孔补强设计方法提供了理论基础．本文算例和实验结果符合得很好．
In this paper, by means of dual-moment weak yielding condition, the complete solution of five kinds of nine kinds of failure mechanisms of densely reinforced spherical shell with open-ended pipes is analyzed and the range of parameters suitable for all kinds of mechanisms is given. Hole reinforcement design provides a theoretical basis. The result of this paper is in good agreement with the experimental results.
