结合施工案例，对近几年国内应用的TBM设备进行总结，从TBM整机寿命、机型、刀盘性能、主轴承密封与润滑、残渣清理等方面对TBM技术的新特色及其发展趋势进行分析。TBM整机使用寿命延长、连续施工能力大大提升；TBM对工程条件的适应性不断提高，出现了多种机型并存的局面；刀盘性能和寿命都得到了较大改善，性价比越来越高；主轴承密封形式有了较大进步，并且密封位置相对可调，有利于保证密封效果、延长使用寿命；残渣清理方式逐步向机械化发展，其应用效果不断提升。对TBM从多个方面进行了人性化设计，TBM技术将在地下工程施工中发挥越来越重要的作用。

The application of TBMs in China in recent years is summarized. The characteristics and development trend of TBM tunneling technology are analyzed in term of service life, type, cutter head characteristics, sealing and lubricating of main bearing and muck cleaning. Conclusions drawn are as follows: 1)The service life and continuous tunneling capacity of TBMs are improved. 2)The applicability of TBMs to the works is improved and various types of TBMs exist. 3)The performance and the service life of cutter heads of TBMs are improved. 4)The sealing effect and service life of main bearing can be guaranteed due to the improvement of sealing mode and the adjustability of sealing positions. 5)The muck cleaning is mechanized. TBM tunneling technology will play a more and more important role in underground projects.
