摘　　要：通过对20个副井井筒与井底连接处破坏实例调查,发现其在设计、施工过程中存在对地质条件掌握不够、结构不合理、设计瑕疵、施工不规范等问题;对其破坏形式进行总结分类,并分析了破坏特点;从地质条件、结构、设计、施工方面探讨了副井井筒与井底车场连接处破坏的原因;研究认为大多数副井井筒与井底连接处的破坏是可以预防和避免的。Through the survey of 20 engineering projects of broken shaft bottom junction, the problems in design and construction process were collected, including insufficient information of geological conditions, unreasonable structure, design flaws, irregular constructions. The damage form in engineering practice was summarized, and the damage characteristics were analyzed, the damage cause was discussed from the geological conditions, structure, design and construction. The results show that, most of the damage at shaft bottom junction can be prevented and avoided.
