Open type landslide debris flow staggered blocking dam group
The open type landslide debris flow staggered blocking dam group is provided on the basis of movement characteristics and accumulation deformation rules of landslide debris flow, the blocking dam group comprises a plurality of blocking dams, the blocking dams are arranged in a channel at the downstream of a landslide body in a staggered mode, the intersection angle of each blocking dam and the channel is 30-60 degrees, and the blocking dams are arranged in the channel at the downstream of the landslide body. The ends, close to the edge of the channel, of the blocking dams are marked as the head ends, the ends, close to the center of the channel, of the blocking dams are marked as the tail ends, and the head ends of the blocking dams are located on the upstream portions of the tail ends of the blocking dams. According to the open type landslide debris flow staggered blocking dam set, the movement speed and kinetic energy of particles in landslide debris flow can be effectively reduced, deposition of landslide debris in a protection structure can be reduced while energy dissipation is achieved, meanwhile, the bearing capacity of a single blocking dam can be effectively reduced, the safety and stability of the blocking dam set can be enhanced, and the service life of the blocking dam set is prolonged. And a new way is provided for disaster prevention and reduction of the landslide debris flow.
本发明基于滑坡碎屑流的运动特点和堆积变形规律，提供了一种开放式滑坡碎屑流交错拦挡坝组，该拦挡坝组包括若干拦挡坝，各拦挡坝交错布置于滑坡体下游的沟道内，各拦挡坝与沟道的交汇角度为30°～60°，将拦挡坝靠近沟道边缘的一端记作首端，将拦挡坝靠近沟道中央的一端记作末端，各拦挡坝的首端均位于各拦挡坝末端的上游。本发明提供的开放式滑坡碎屑流交错拦挡坝组可有效减小滑坡碎屑流中的颗粒的运动速度和动能，在实现消能的同时可减少滑坡碎屑在防护结构内的淤积，同时可以有效降低单个拦挡坝的承载力，可增强拦挡坝组的安全性和稳定性，为滑坡碎屑流的防灾减灾提供了新的途径。
