隧道-滑坡体系的研究进展和展望

Progress and Expectation of Research on Tunnel-Landslide System

在山区修建公路、铁路隧道时,常遇到隧道从滑坡体内及周边穿越的现象,这些滑坡或因隧道开挖而蠕动,而隧道因坡体滑动而产生变形、开裂等病害。研究隧道-滑坡体系的变形机理及防治技术具有重要的指导意义。自20世纪60年代以来,我国铁路和公路部门先后针对这一问题开展了科学研究和工程应用,笔者从研究历程、取得的成果、存在的问题及今后的研究方向与思路几个方面作一简要综述,希望对今后的研究和生产实践中起借鉴和指导作用。

While constructing tunnels of highway or railway in the mountainous area,it is often to meet the situation that tunnels pass through the landslide site. It is of significance to research the deformation mechanism and prevention technology of tunnel-landslide system. Since 1960 s,the railway and highway departments of China havecarried out scientific research and engineering applications to solve this problem.Proposing to give guidance and reference for the further studies,the authors conducted a brief overview from the research process,aspects of the achievements,problems and future research directions and ideas.
