Grouting method has been widely used as a measure to compensate the ground settlement. Current research mainly focuses on the principle of grouting and the recovery of the settlement. However, the influence of soil parameters and injection parameters on the horizontal displacement of tunnel has not been systematically studied. Therefore, based on a field grouting test of a project in Tianjin, this paper used strain method to simulate the grouting process, and studied the influence of soil conditions, grouting amount, grouting distance, grouting length and grouting depth range on the horizontal deformation of soil. The results show that the maximum horizontal displacement of soil caused by grouting is located near the top of the grouted zone. Soil strength and stiffness have little influence on grouting effect, which indicates that the applicability of grouting to control horizontal displacement is wide. The horizontal displacement of soil near the grouting point increases rapidly with the increase of grouting amount and slowly when it is far from the grouting point, and the horizontal displacement of soil decreases rapidly with the increase of grouting distance. Therefore, the distance between the grouting point and the correcting object should be shortened. When the grouting length is small, the influence range of grouting is concentrated and the maximum displacement of soil is large. On the contrary, the influence of grouting is relatively dispersed and uniform. The grouting length should be selected according to the distance of grouting and the range of depth of correcting object to maximize the effect of grouting correction.
