Because rock tunnel boring machines (TBMs) have been
used in China for nearly 60 years, understanding the development history of the
TBM tunneling technology in China is useful to learn its current status
correctly and determine the development trend in the next step. Accordingly,
the authors thoroughly examined five development stages of the current status
of TBM tunneling technology in China in detail from 10 perspectives, including
scale, distribution area, distribution field, excavation diameter, construction
method, construction period, type, brand, component, and construction
enterprise. The development trends of TBM tunneling technology in China are put
forward as follows: (1)On a larger scale, it will go through a fluctuating
development process of rising, leveling, falling, and stabilizing, and is
currently rising. The western region will be the primary focus, and the water
conservation, hydropower, and rail transit projects will be the primary fields
soon. (2)The combination of the TBM method and drillandblast method will exist for a long time, whereas the TBM method will
take a larger proportion and bore longer in the same project. (3)The support
technology system will usher in significant changes. (4)The TBM tunneling
technology in complex geology is being fully developed and practiced, and a
significant breakthrough is about to be achieved. (5)New TBMs, including
inclined shaft TBM, vertical shaft TBM, micro TBM, superlarge diameter TBM, composite (multimode) TBM,
specialshaped crosssection
TBM, etc.〖KG-*3〗, have been
developed and applied, and are making great progress. They will become popular
once they have reached maturity, and the key TBM components will be
nationalized in the future. (6)The big data technology, artificial intelligence
technology, and 5G technology will promote intelligent TBM tunneling.
