The traditional method can not guarantee the construction of connection gallery in Xi’an Metro. The WSS grouting reinforcement methods in tunnel are proposed. The keys of the mentioned method are the position of the grouting holes and the grouting matching and parameters. The paper can provide references for the construction of connection gallery of Xi’an Metro.
