摘　　要：立井井筒穿越厚粘土层的施工一直是冻结法凿井的技术难点。通过对厚粘土层冻结井壁力学特性的现场实测,深入分析了井壁压力变化规律、井壁的环向和竖向受力特性。A mine shaft sinking through a thick clay stratum is always the technical difficulty of the mine freezing shaft sinking. With the site measurement of the mechanics features of the mine freezing shaft wall in the thick clay stratum, paper in detail analyzed the pressure variation law of the mine freezing shaft wall and the circular and vertical stressed features of the mine freezing shaft wall.
