Abstract:

Backfilled grouting is an essential step in shield tunnelling. In the paper, the main problems that are to be solved in the field of backfilled grouting are analyzed on basis of the characteristics of backfilled grouting; the distribution characteristics, research institutions, research groups and fund sponsorships of research papers in backfilled grouting are analyzed; the research status of backfilled grouting of shield tunnels are summarized, and the development trend of backfilled grouting of shield tunnels is discussed. The results showed that: 1) Researches on conventional geotechnical engineering have great reference value for researches on the backfilled grouting of shield tunnels; 2) In the aspect of paper quality and paper quantity, papers and research achievements on backfilled grouting are still little, and universities have significant advantages in this aspect; 3) The national fund has obvious effect in promoting the researches on backfilled grouting; 4) As to the status of researches on backfilled grouting, there are many researches specialized on grouting materials, the researches on grouting parameter control and grout diffusion mechanisms are still in the theoretical stage, and there are little researches specialized on grouting effect evaluation. 
