冻结管保温条件下井架基础变形研究

Research on derrick foundation deformation under frozen pipe insulation condition

以某副井冻结井筒为依托,针对冻结工程中井架基础受到冻胀力作用发生变形的问题,通过数值模拟和现场实测数据分析,得到了冻结管保温后冻结期内井架基础变形规律,对工程施工具有重要意义。

Based on a frozen shaft of auxiliary shaft, according to the deformation problems of derrick foundation under frost heaving force in fro- zen engineering, through the numerical simulation and field measurement data analysis, obtained the deformation law of derrick foundation after frozen pipe insulation and freezing period, had great significance to engineering construction.
