摘要
冻结法凿井是利用人工制冷技术暂时冻结加固井筒周围不稳定地层并隔绝地下水后再进行开凿井筒的特殊施工方法。采用冻结法施工的井筒,完成后地层中留有大量的冻结孔。本文基于某工程实例,主要通过数值计算温度场分析利用冻结孔作为地源热泵埋地换热器的可行性,以实现浅部或深部地层冷量和热量的利用。
Freezing Shaft Sinking method is a particular construction method by using artificial freezing technology to freeze and reinforce the unstable stratum,isolate groundwater temporarily before sinking shaft.There are many freezing holes left after finishing of shaft construction.Based on a project case,the paper analyses the feasibility of untilizing these freezing holes to be underground heat exchanger of ground source heat pump mainly through numerical simulation of thermal field to make use of the heat and cold energy in shallow or deep ground.
