Studies on status and prospects of anti-slide shaft technology

On one hand, anti-slide shaft technology can overcome the problems of blocking the seepage and drainage path in the slope by traditional anti-slide piles. On the other hand, it can reduce the excavation quantities when the vertical drainage and anti slide structures are separately constructed. Besides, it can fully provide the hydration-heat dissipation surface to ensure the overall structure quality. It has been an important technology in modern landslide prevention engineering, and the novel one of geological disaster, hydrogeology and underground engineering in recent years. The anti-slide shaft technology involves hydrodynamic mechanics and solid mechanics, as well as hydrodynamic model, structural model, engineering geological model, etc. Besides, its promoted application is restricted by some problems, such as the lack of mature theoretical system, the relatively complex of this spatial structural combination, and the difficulty of the construction technology. Thus, it is necessary to carry out targeted
