冻结壁解冻过程中斜井受力模型试验设计

Model Test Design of Stress on Inclined Shaft during Thawing Process of Frozen Wall

以陕北地区某矿主井冻结工程为参照原型,将相似理论和模型试验的研究方法应用于饱和砂层冻结壁解冻过程,进而探求解冻过程中的井筒致灾因素,为饱和砂层冻结施工和解冻阶段施工工艺改进提供试验依据。

To explore the cause of inclined shaft failure factor in the thawing process and provide experimental basis for freezing construction in saturated sand and improvement of construction technology in thawing stage, the similarity theory and model test are applied to the frozen wall thawing process, which refers to a main shaft freezing engineering of a coal mine in northern Shaanxi.
