    DEVELOPMENT OF TBM-EXCAVATION TECHNOLOGY AND ANALYSES |COUNTERMEASURES OF RELATED ENGINEERING GEOLOGICAL PROBLEMS

    • This paper presents a summary of development, applications and existing problems in tunnel construction of TBM for the past half a century by studying a great deal of data and projects. It is shown that TBM has become the priority of the tunnel construction method and has a great potential for future tunnel construction. From the points of rock mechanics and engineering geology, the authors analyze the engineering hazards such as TBM jamming, deformation and breakage of linings caused by large deformation of soft rock, water flow, rock burst and so on. In addition, the countermeasures adopted in construction are also discussed. With the extensive application of TBM-excavation technology in China in the near future, a better understanding of the complicated engineering geological conditions and timely adjustment of construction precepts are becoming key factors that influence construction safety and economic benefit.
