摘要
通过对大量文献资料和工程实例的研究,论述了TBM(隧道掘进机)近半个世纪发展及其在隧道建设中的应用现状和问题。对大量国内外工程实例分析后发现优先采用TBM掘进技术已成为未来隧道建设总的发展趋势。从岩石力学和工程地质角度对岩石TBM掘进过程中遇到的诸如软岩大变形、突水、岩爆等不良工程地质问题导致卡机或管片变形、破损等工程事故进行了剖析,并对采用的工程处理措施作了总结对比。随着今后TBM掘进技术在我国大规模应用,对复杂工程地质条件的客观全面认识和施工方案的及时调整成为影响施工安全和经济效益的关键因素。
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.
