摘　　要：文章统计了国内外双洞隧道穿越滑坡的典型工程案例,详细阐述并分析了目前隧道开挖诱发滑坡失稳的机理、滑坡影响下的隧道响应特征、滑坡的监测及预测技术、隧道-滑坡体系处治技术等方面的研究进展。提出了当前并行双洞隧道穿越滑坡工程面临的5大问题,即双洞隧道穿越滑坡失稳演变过程、滑坡稳定性、隧道结构响应特征、滑坡失稳防控技术及滑坡变形智能监测技术;针对目前并行双洞隧道穿越滑坡面临的挑战,指出精细化数值仿真模拟、组合创新滑坡锚固体系及材料、新型隧道支护体系、基于空-地一体化的滑坡智能监测技术是今后重要的研究方向。In this paper,the typical engineering cases of double-tube tunnels crossing landslides at home and abroad are summarized,and the research progresses in the mechanism of landslide instability induced by tunnel excavation,tunnel response characteristics under the influence of landslide,landslide monitoring and prediction technologies,treatment technologies of tunnel-landslide system and so on are described and analyzed in detail.Then,five current major problems faced by the parallel double-tube tunnel works crossing landslide are put forward,namely,evolution process of landslide instability,landslide stability,tunnel structure response characteristics,landslide instability prevention and control technology and intelligent monitoring technology of landslide deformation.In view of current challenges faced by parallel double-tube tunnels crossing landslides,it is pointed out that refined numerical simulation,combined innovation of landslide anchorage system and materials,new tunnel support system and air-ground integration based intelligent landslide monitoring technology would be important research directions in the future.
