The characteristics of the fullface
tunnel boring machines (shields and TBMs) technologies in different development
stages in China are analyzed and discussed. The development of the shield/TBM
technologies in 〖HJ4mm〗China is
divided into six stages, i.e., hard and independent exploration stage, foreign
manufacturing and foreign construction stage, foreign manufacturing and
independent construction stage, joint manufacturing and independent
construction stage, independent manufacturing and independent construction
stage, and goingabroad stage. The achievements of the
shield/TBM technologies in China are systematically summarized from the aspects
of major construction projects, major shield/TBM, and development characteristics.
The following conclusions are drawn: (1) The construction of major projects,
such as superlong mountaincrossing
tunnels represented by Gaoligongshan tunnel on DaliRuili
railway, underground urban tunnels represented by Chunfeng tunnel in Shenzhen,
and sea/rivercrossing tunnels represented by Haiwan
tunnel in Shantou, promotes the unprecedented progress of shield/TBM
technologies. (2) Major shield/TBM technologies, typically represented by largediameter slurry shield technologies, noncircular
shield/TBM technologies, and shield/TBM technologies in complex environment,
have made great breakthroughs in terms of independent design and manufacturing
capability. (3) The shield/TBM technologies demonstrate the characteristics of
developing from the conventional crosssection to the
superlarge/small crosssection,
from single mode to multimode, from the circular crosssection to noncircular crosssection, and from the conventional horizontal direction to multidimension. Ultimately, the development trend of shield/TBM is
analyzed from aspects of diversification and intelligentization, and the
technical system for the intelligent shield/TBM is discussed in aspects of
"sensibility", "excavatability", and
"controllability".
