Abstract：
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.
