【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.更多还原
