| 中文摘要: |
| 为了详细研究淮南矿区冻土的物理力学性能,为冻结法施工提供设计参数,以刘庄煤矿东风井典型粘土层为研究对象,按照部颁煤炭行业标准(MT/T593-1996),在冻结冻土力学性能室内进行了人工冻结的蠕变试验。根据冻土单轴蠕变实验数据,分析总结出冻土在单轴应力条件下的应力、应变、温度和时间相互作用的关系,从而得到蠕变本构方程和蠕变规律,该规律对淮南矿区井筒冻结设计和施工具有重要的借鉴意义。 |

| For a detailed study of the physical and mechanical properties of permafrost in Huainan mining area, to provide design parameters for the frozen method to Liu east wind Coal Mine Well typical clay layer for the study, according to the Ministerial coal industry standards (MT / T593-1996),artificial freezing of creep test have been taken place in mechanical properties of permafrost freeze room.According to permafrost uniaxial creep test data, analyze and conclude the relationship of interaction between stress, strain, temperature and time of permafrost under uniaxial stress conditions,resulting Creep and creep law, the law has an important reference for Huainan Mining freeze wellbore design and construction. |
