Abstract: The impact factors of the construction of apron sections of the doublearch shallow buried metro tunnel at the Xixian Station in Xi′an Metro Project on the subsidence of the ground surface are discussed in this paper. The roles of the small leadtube advanced grouting in the ground subsidence control are also presented. The project practice indicates that it is necessary to strengthening the soil at some special areas.

Key words: ShallowBuried Tunnels, Ground Subsidence, Radial Grouting
