Abstract
Description
technical field
[0001] The invention belongs to the technical field of prevention and control of geological disasters, and relates to a flow-through debris flow retaining dam and a group of dams. Background technique
[0002] At present, the role of debris flow retaining dams is generally to block, and its purpose is mainly to hold water and sediment, change the conditions of water and sediment delivery, adjust the discharge of water and sediment, and stabilize slopes and valleys. When the effective storage capacity in the retaining dam is filled with mud and sand, the retaining and regulating functions will be lost, and the disaster prevention and mitigation functions will be greatly weakened.
[0003] After the effective storage capacity in the retaining dam is filled with mud and sand, a large amount of solid loose matter is stored in the ditch, and the pressure of the debris flow accumulation on the retaining dam is high. Once the retaining dam collapses, the solid loose...
