| 摘 要： | 通过对淮北、徐州等矿区井壁发生破坏情况的分析，指出了竖向附加力是导致井壁破坏的根源。编制了井壁结构空间轴对称问题弹塑性有限元程序，并采用它对上述破坏井壁进行了计算分析，得到了地层沉陷时井壁承受竖向附加力的数值，从而可为井壁设计提供参考依据

| Abstract: | Based on the analysis of the shaftlining damaged cases in Huaibei and Xuezhou mine areas, the result indicates that the main cause for damage is vertical additional force. An elastic and plastic finite element program is worked out for the shaftlinings and it is applied to calculate and analyze the damaged shaftlinings , the value of vertical additional force is obtained under ground subsident condition, the results provide basis for the shaftlining design. |
