Abstract Research purposes: In constuction of submarine tunnel，the grouting formula is important for reinforcement of the surrounding rock and water—-proof．The strength and durability of the grouting materials are the key elements for ensuring the long—term normal service of the submarine tunnel．The chemical and physical corrosions caused by the environment change of sea water and its own effect of the grouting materials are the main reasons for the corrosions to the grouting materials．The orthogonal experiments were conducted to the grouting materials comprised of portland cement，slag—portland cement and water glass to analyze the basic performance of the slurry comprised of Portland cement， slag—portland cement and water glass．With the orthogonal experiment method，the matching ratio of slurry Was optimized by taking the compress—resistant capacity as the major factor．
Research conclusions: From the comparison between the compress—resistant capacities of two specimens at the same age of two kinds of different grouting materials it was found out the corrosion—-resistant capacity of the slag—Portland cement Was much better than the Portland cement．The optimized grouting slurry Was used to reinforce the ground of the service tunnel of Jiaozhou Bay in Qingdao，obtaining a good reinforcement result．
