The construction technologies, including setting antecedent tunnel enlarging after tunnel, are used in the construction of Xiangjiang tunnel on Yingpan road in Changsha. Technologies, such as advance geological prediction, advance pregrouting, advance supporting system and other assistant technologies, are used. The construction of the tunnel is successful and the construction scheme is shortened. The paper can provide references for similar projects in the future.
