摘　　要：冻土地区的地基土冻胀问题是影响基础稳定的关键因素。改进了常规防冻胀处理措施,提出了包括采用锥柱基础、换填非冻胀性材料、涂抹润滑剂以及采用玻璃钢模板等6种处理方式,工程实践证明该防冻胀措施合理、有效。Frost-heaving is the key factor that impacts the stability of foundation in the frozen-soil region.In this paper,the conventional anti-frost heaving measures are improved by six treatment measures,such as cone cylindrical foundation,the replacement of heaving material,lubricant smearing and the application of glass steel formwork.These measures have been proved reasonable and effective through engineering practices.
