摘要
根据在冻结法凿井工程中冻结器纵向测温的经验摸索,建立了停冻后的单孔冻土柱升温的数学计算模型,借助现代数学工具Maple6软件,将公式数字化和图形化,从而揭示了在瞬时升温过程中单孔冻土柱温度分布与时间、冻土柱半径之间的关系,为冻结器内测温、监控冻结井筒温度场提供一种理论依据,并给出了一个应用实例.
According to the practice of temperature measuring along the freeze pipe during the intermission of freezing in the shaft sinking, a mathematical model of single freezing soil pole was established in order to calculate transit rising temperature field. By using the modern software of the Maple6, the formula is figured out with chart. The basic laws showing the relationship among temperature, time and radii of the freezing soil pillar is brought forth, which offers a way to manage the temperature field of the ground freezing shaft. Finally, an case is introduced to suitably apply to the theory.
