Background

The natural barrage formed by landslide is extremely poor in safety, stability, erosion resistance and the like, and can break the dam at any time along with the rise of water, so that great danger can be formed for upstream and downstream. At present, no safe, reliable and effective treatment method exists at home and abroad, and the existing treatment method mainly comprises blasting flood discharge, manual excavation of flood discharge channels and the like.

Blasting flood discharge: blasting flood discharge is generally completed by burying explosives in artificial embankments and dams under the condition of emergency and on the premise that personnel are successfully transferred. However, explosion flood discharge causes a great flooding disaster to the downstream, and vibration generated by explosion easily causes secondary landslide.

The governing principle is that the water level of a dammed lake is controlled according to the dredging water flow, and the overflow of the lake water is strictly controlled, so that the influence on the downstream is small. However, because the dam body of the damming dam has large engineering quantity and long excavation time, the soft dam body has the possibility of breaking the dam at any time along with the rise of the water level, and great potential safety hazards exist for emergency personnel.
