摘　　要：对冻土融沉注浆的机理以及利用强制解冻方法融沉注浆进行土体加固的方法作了详细介绍,并结合某地铁联络通道的融沉注浆施工,说明了对冻结土体进行分区强制解冻融沉注浆是控制地表沉降的有效方法.[Abstract] The settlement of soil strengthened through freezing is likely to cause the deformation of both the ground and the tunnel in the course of natural thawing if managed improperly. This paper makes an introduction of the mechanism of thaw settlement grouting, and the method of reinforcing soil by forced thaw settlement grouting. Combined with the introduction of the thaw settlement grouting case in a subway contact channel project, this paper states that the method of thaw settlement grouting after divisional forced thaw is an effective way to control ground settlement.
