Background
The construction of hydropower stations is often accompanied by the problem of landslide mass management, the problem of superelevation landslide mass management is a great problem, and the landslide mass is generally managed by adopting engineering measures such as arranging anti-slide piles, prestressed anchor cables, weight reduction and back pressure, retaining walls, anchor cable piles and the like. Although the engineering measures for governing the landslide body are numerous, the key of the engineering design is to select a safe, reliable, economic and reasonable measure.

If the high-speed landslide body is driven reversely, the ultrahigh landslide body is not processed, and the hydraulic structure and the corresponding equipment can resist surge impact and reservoir water level surge caused by collapse of the high-speed landslide body after the landslide body naturally collapses. Through analysis, the scheme is lower in cost and safer in engineering compared with the conventional engineering measures.
