The number of tunnels constructed in China has been increasing year by year; however, geological disasters of water inrush often occur in the process of tunnel excavation. Grouting is a common approach to solving this problem, it also plays an important role in the plugging and reinforcement of underground engineering. Based on the review of the grouting technique development in tunnel engineering, we summarized the research status of model tests, grouting materials, advanced forecast technology, grouting control system and grouting effect evaluation methods, sorted out the advantages and disadvantages of different techniques, and looked into the development trends in all aspects. Finally, a set of tunnel intelligent grouting control system was put forward based on the analysis of past engineering practice and the development of current intelligent grouting field, in the hope of providing reference for the research of grouting field and tunnel construction in China.
