摘　　要：针对西部地区深基岩冻结井筒外层井壁结构优化设计方案,本次模型试验基于相似理论对我国西部地区某矿井冻结井筒外层井壁的力学特性进行研究,得到外层井壁的应变、应力、径向位移与水平荷载之间的关系曲线,并对其受力机理进行探讨。The model test on the basis of the similarity theory is built to research the outer shaft wall mechanical properties of a mine freezing shaft, for the optimizing design scheme of the outer shaft wall structure of deep freezing bedrock shaft in west area. The relationship between the horizontal load curve and the strain, stress and radial displacement of outer shaft wall, and its working mechanism is discussed.
