深厚基岩立井冻结井壁的研究

摘要

立井基岩冻结井壁的理论计算至今尚处于探索阶段,根据孟村矿井对回风立井冻结压力和水压力的监测结果,对作用于立井井壁荷载给出了相应的公式,并从工程实践对检测结果结论进行了客观的分析,从而揭示了利用中东部表土层冻结井壁结构设计理论应用在西部深厚基岩上存在的相关问题.该研究为我国西部矿区立井基岩冻结井壁的设计提供了借鉴.%The theoretical calculation of vertical shaft freezing wall is still in the exploratory stage till now.Based on the monitoring results of the freezing pressure and water pressure of the vertical shaft in Mengcun Coal Mine,the corresponding formulas was given for the vertical shaft wall load.The test results were analyzed combining with engineering practice,so as to reveal the relevant application problems for the deep bedrock in the western part of China using the design theory of the frozen shaft lining in the middle and eastern parts of the country.The paper can provide references for the design of vertical shaft freezing shaft wall in western China.
