本文在依相似理论建立的竖井模拟试验台上,对位于特殊地层中的立井井壁受力问题进行了模拟研究,首次证实了粘土层对井壁作用有纵向附加力,并得到了该力的数值、分布及变化规律。得出附加力是导致矿井井壁结构破坏的重要因素的结论,指出位于特殊地层的立井井壁结构设计应当采用三维空间理论进行计算。 In this paper, based on the similarity theory to establish the shaft simulation test stand, the shaft wall in a special formation in the stress study conducted a simulation study for the first time confirmed that the role of the clay layer on the wall longitudinal additive force, and get the force Numerical, distribution and variation. It is concluded that additional force is an important factor leading to the destruction of mine shaft lining structure. It is pointed out that the design of vertical shaft lining in special strata should be calculated by using three-dimensional space theory.
