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。
In order to further carry out the research on large deformation mechanism of soft surrounding rock tunnel, we have searched the domestic and foreign experts and scholars in recent years The paper reviews the latest research status and progress of large deformation of tunnels and summarizes the main methods and means of large deformation control technology for tunnels in soft and weak surrounding rocks at present and clarifies the development direction and trend of the future research on this subject. It is of great practical significance to carry out the research on large deformation mechanism and construction mechanics characteristics during the construction of deep soft surrounding rock with high ground stress and to explore new ideas and methods for controlling large deformation of surrounding rock actively.
