摘　　要：本文根据砼强度理论对淮北等矿区井壁破坏应力特征和破坏形态进行了理论分析,并与模型试验结果和现场井壁实际破坏特征加以对比,从而论证了引起井壁破坏的应力状态及其外荷载条件,并阐述了荷载产生的原因.In this paper, the stress states and loads causing the failure of shaftlinings in Huaibei and other mine areas are demonstrated by the analysis of the failure stress states and the patterns of the practical shaftlinings in the light of concrete strength theory, and by comparing practical failure states with the results of model experiments in the lab.
