TBM掘进技术的发展应用及相关工程地质问题探讨

The Development & Application of TBM, and Discussion of Correlated Engineering Geological Problems

阐述了TBM(隧道掘进机)半个世纪以来的发展及其在国内外隧道建设中的应用,指出优先采用TBM掘进技术进行隧道开挖已成为未来隧道建设总的发展趋势;并在分析大量国内外工程实例的基础上,结合TBM施工中的经验及教训,对TBM掘进过程中存在的诸如断层破碎带、挤压地层、地下水、岩溶等相关工程地质问题进行了探讨,并提出了相应的处理措施。

This paper expounded the development and application in tunnel construction all over the world of TBM in the past half a century, pointed out that excavating tunnel by TBM has become the developmental direction of tunnel construction in the future. On the base of analysis of a great deal engineering example, combining the experience and lessons obtained in TBM construction, the authors discussed correlated engineering geological problems existing in excavation, such as fault fractured zones, compressional stratum, groundwater and karst etc.. At the same time, the corresponding countermeasures particularly for reference were introduced.
