摘　　要：安徽淮南刘庄煤矿主井井塔地基工程采用了人工冻结法施工,因而主井井塔地基土发生冻胀和融沉的变化。为了工程的安全和井塔的稳定,本文对主井井塔地基的人工冻融土进行了冻胀和融沉模拟试验,并对试验数据进行分析和计算。本文对人工冻融土冻胀与融沉性质的研究,填补了我国在这方面研究的不足,为今后该方面的工程施工提供了参考依据。Artificial freezing-thawing method was applied to foundation construction of the main shaft tower of the the Liuzhuang coalmine, Huainan, so the change of freezing swelling and thawing subsidence happened to the foundation soil. For the engineering safety and shaft tower stability, this paper made a simulating test on freezing swelling and thawing subsidence properties for the artificial freezing-thawing soil, analysed and calculated the testing data. This study has filled the deficiency in this area in China and provided a basis for reference for the similar engineering work.
