【摘要】 采用大型有限元程序对某冻结井筒合理的冻结壁厚度值进行了计算研究,获得了冻结壁的径向弹塑性及蠕变位移规律,研究表明:冻结壁厚度取12 m,平均温度取-20℃,可保证冻结壁的安全。
【Abstract】 A large-scale finite element programming is used to study on the appropriate thickness of frozen shaft lining. The regularities of radial elastoplasticity and creep deformation of the frozen shaft lining are found. The study indicates that the frozen lining is safe when its thickness is 12 m and the average temperature is -20℃.
