摘要
高地应力深埋软弱围岩隧道在施工过程中常常会发生大变形地质灾害,针对这一工程难题,为了进一步开展软弱围岩隧道的大变形机理研究,检索了近几年来国内外专家学者所著的相关文献与书籍,分析了有关隧道大变形最新的研究现状与进展,总结了目前软弱围岩隧道大变形控制技术的主要方法与手段,明确了该课题未来研究的发展方向与趋势,对系统开展高地应力深埋软弱围岩隧道施工过程大变形机理和施工力学特性研究,积极探索控制围岩大变形的新思路、新方法有着一定的工程实际意义。
Soft rock tunnel which is buried deeply in high ground stress is often accompanied by large deformation of geological disaster in construction process, which seriously affects the safety of construction. In order to overcome this engineering problem and to further reveal the mechanism of large deformation in sort rock tunnel, in this paper related literature and books written by the experts and scholars at home and abroad in recent years are referred, the latest research status and progress of the serious deformation are analyzed, the methods and means to control the large deformation in soft rock tunnel are summarized, and the development direction of this question＇s future studies is pointed out. It is meaningful and valuable to carry out the systematic studies in mechanism of large deformation in soft rock tunnel and mechanical characteristics in the process of construction and explore the new ways and methods that control the large deformation in soft rock tunnel.
