An increasing number of complex geological conditions
are encountered during tunnel boring machine (TBM) construction; thus, advanced
treatment is required to reduce or avoid frequent TMB jamming under complex
geological conditions. In this study, 10
existing treatment techniques are reviewed to analyze geological problems such
as broken, weak, waterrich, complete, and hard rocks, as
well as rockburst. Advanced treatment techniques include (1) the advanced
treatment of and ahead of tunnel face, including cutterhead cleaning, advanced
grouting of tunnel face, surface grouting, and artificial joints; (2)
postpositioned advanced treatment techniques applied to the tail or behind
shields, including advanced grouting, advanced smallduct
grouting reinforcement, and advanced pipe shed reinforcement; and (3) advanced
treatment techniques of pilot tunnel methods applied to proper positions,
including the smallpilot tunnel method, pilot tunnel
method, and stress release method of pilot tunnels in advance. Advanced
treatment of TBM construction can be achieved by (1) reducing the construction
proportion of TBM in unfavorable geological tunnel sections; (2) improving the
geological adaptability of TBM construction methods; (3) improving the accuracy
and timeliness of advanced geological prediction; (4) creating dynamic designs
and performing rational decision making; and (5) improving management systems,
such as norms, standards, and quotas, and promoting the scientific application
and popularization of TBM.
