摘　　要：冻结法主要适用于含水量较大、结构不稳定的松软泥岩和裂隙发育的含水岩层区域的井筒开凿施工,具有冻结强度高、冻结范围易控制以及经济、环保的技术优点,在井巷施工建设领域具有广泛应用。在使用冻结法进行井筒施工时,有时会出现冻结井壁破裂、冻结管断裂、工作面底鼓、冻结壁变形等问题,严重影响井筒施工。而这些也是井筒冻结法施工过程中的常见问题,本文对此进行了探讨。The freezing method is mainly suitable for wellbore excavation in areas with large water content and unstable structure in soft mudstone and water-bearing rock formations with developed cracks.It has the technical advantages of high freezing strength,easy control of the freezing range,economy and environmental protection.It has a wide range of applications in the field of construction.When the freezing method is used for shaft construction,sometimes problems such as freezing shaft wall rupture,freezing pipe fracture,working face bottom heave,and freezing wall deformation may occur,which seriously affect the shaft construction.These are also common problems in the construction process of shaft freezing method,which are discussed in this article.
