盾构隧道壁后注浆研究现状及发展趋势

Research Status and Development Trend of Back-filled Grouting of Shield Tunnels

壁后注浆是盾构隧道施工过程中必不可少的环节。针对盾构隧道壁后注浆的特点,分析壁后注浆研究拟解决的主要问题,同时对壁后注浆研究论文的分布特征、研究机构、科研群体及基金资助等情况进行分析,综述盾构隧道壁后注浆研究现状,探讨其未来研究的发展方向。结果表明:1)传统岩土工程研究对盾构隧道壁后注浆研究具有较大的参考价值;2)在论文质量与数量方面,该领域研究成果依然不多,且高等院校的优势明显;3)国家基金的资助对盾构壁后注浆研究的促进作用巨大;4)壁后注浆研究现状中,对浆液材料研究较多,注浆参数控制和浆液扩散机制依然停留在理论阶段,而对注浆效果评估的研究依旧不多。

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.
