The curtain grouting constructions in 3 different hydrogeological sections of the main tunnel in No. 3 inclined shaft work lot of Xiangshan tunnel are compared. Three different grouting schemes, i.e., fullface curtain grouting, surrounding curtain grouting and local curtain grouting, are discussed. The influence of different grouting schemes on the construction efficiency under different hydrogeological conditions is analyzed. Optimal grouting schemes are determined, the grouting technology and the construction organization technology are optimized, which achieves better controlled construction cost and reduced construction period.
