摘要
通过对隧道掘进机的分类、隧道掘进机技术的研究现状以及隧道掘进机技术研究和发展趋势的调研和探讨,提出:1)根据掘进岩土体强度的不同,隧道掘进机大致可以分为岩石隧道掘进机和盾构;2)目前岩石隧道掘进机的研究热点问题主要包括滚刀破岩机制和施工预测模型的建立2个方面,而盾构主要研究内容集中在掌子面稳定、施工过程控制和地表沉降研究3个方面,虽然这些研究都取得了较大进展,并且部分已经有效地应用到实际工程建设中,但解决得不够透彻,还有待于进一步研究;3)隧道掘进机技术的研究发展趋势将集中在掘进力学机制的完善、复杂地质条件下掘进机制与施工过程控制研究和复合掘进机技术的发展等方面,这些会给隧道掘进机技术的研究和发展带来挑战和契机。
In this article, the classification of tunnel boring machines （TBM）, the state-of-the-art of studies on tunnel boring machine technology, and the trend of study and development of tunnel boring machine technology are studied and discussed. Conclusions drawn are as follows ： 1 ） According to the strength of the rocks and soils bored, tunnel boring machines can be divided into rock tunnel boring machines and shield machines. 2） The hot topics of studies on rock tunnel boring machines include the rock-breaking mechanism of disc cutters and the establishing of TBM performance prediction models. On the other hand, the hot topics of studies on shield machines include the stability of working face, the control of boring process and the study on ground surface settlement. 3 ） Studies on tunnel boring machine technology will focus on the improving of the boring mechanism, the boring mechanism and the boring process control under com- plex geological conditions, and the development of composite boring technology.
