| 摘 要： | 通过对黄淮地区井筒破裂现象的案例分析，发现这一地区的井筒在破裂位置、破裂时间及破裂形态等方面存在诸多相似点，透过这些表象从理论上对破裂原因作了分析，得到“表土沉降和温差所引起的负向摩擦力是井筒破裂的重要致因”这一结论，并针对性地提出具体而简单可行的防治措施。

| Abstract: | The case studies of shaft lining rupture phenomenon in Huanghuai region showed that there are many similarities in location, time and form of shaft lining rupture. Theoretical analysis of the rupture reason was made and it＇s concluded that the negative friction caused by surface subsidence and temperature difference is the important reason of shaft lining rupture. Some concrete and simple prevention and control measures were given. |
