Abstract

The invention discloses a mud-rock flow risk assessment method and device for a mud-rock flow basin system. The method comprises: obtaining the state variables of the terrain subsystem, the state variable of the solid material source subsystem and the state variable of the hydrodynamic subsystem of the mud-rock flow basin to be evaluated; The state variable of the terrain subsystem, the state variable of the solid matter source subsystem and the state variable of the hydrodynamic subsystem are used to construct the state variable of the debris flow basin system; the information entropy of the debris flow basin system is constructed by using the state variables of the constructed debris flow basin system Model; using the constructed debris flow basin system information entropy model to carry out risk assessment on the debris flow basin to be assessed.

Description

technical field

[0001] The invention relates to the technical field of disaster risk assessment, in particular to a debris flow risk assessment method and device for a debris flow basin system. Background technique

[0002] Debris flow refers to a special torrent that carries a large amount of solid materials such as mud, sand, and stones in valleys or hillsides under the action of surface water formed by precipitation, dam breaks, or melting ice and snow. , has strong destructive and impact power, and poses serious threats and dangers to mountainous towns, villages, transportation, electricity, communications, water conservancy, mining, agriculture, and ecology. As we all know, debris flow disaster is a system problem, and the debris flow system is an open dynamic system. The energy distribution and interaction results of the system directly determine whether the watershed is a debris flow ditch and the risk of debris flow. However, there is no relevant research and discus...

Embodiment Construction

[0068] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0069] The purpose of the present invention is to solve the key judgment and evaluation method problems existing in the disaster prevention and mitigation work such as the identification of potential debris flow ditch and the risk of debris flow. Taking system energy as the main line, based on the information entropy theory and the principle of debris flow generation, establish a debris flow The state equation of the watershed system and the information entropy model can realize the real-time judgment of the state of the debris flow watershed system, and can be widely used in the fields of potential debris flow ditch identification, debris flow risk assessm...
