Abstract

The present invention discloses an impact force simulation device during a debris flow movement erosion-deposition process. The device comprises a supply box and an accumulation plate which are fixed on a support separately, and a circulation groove is connected between the supply box and the accumulation plate. The circulation groove is equipped with the debris flow laser mud level meters and the optical fiber pressure sensors according to different gradients, vibration string pressure sensors are arranged on the accumulation plate, and a camera and a data acquisition unit are also arranged on the support. The simulation method comprises the steps of 1 setting the gradient of the circulation groove and the accumulation plate; 2 setting a boundary condition; 3 simulating a debris flow medium; 4 setting an initial condition; 5 determining a time step; 6 setting a beta value; 7 acquiring and tidying experiment data; 8 cleaning an experiment platform. According to the present invention, the impact force simulation and experiment during the debris flow movement erosion-deposition process can be realized, and the circulation groove can be adjusted according to different gradients and different boundary conditions. According to the present invention, the circulation groove boundary conditions can satisfy the experiment requirements of the debris flows of different volume-weights, thereby obtaining the impact forces and the accumulation ranges under different return periods and during the movement erosion-deposition process.

Description

technical field [0001] The invention relates to the technical field of debris flow impact force simulation equipment and simulation experiment application, in particular to impact force simulation equipment and a simulation experiment method during the erosion and deposition process of debris flow movement. Background technique [0002] The impact force simulation equipment during the erosion and deposition of debris flow movement, as the name suggests, is a device used to simulate the impact force during the erosion and deposition process of debris flow movement. There is no equipment in the prior art that can realize multi-parameter rapid simulation and testing, which is difficult to meet the needs of people's production and life and disaster prevention and mitigation projects; in addition, there is no standard simulation test method for people to use. Contents of the invention [0003] In view of the deficiencies in the above-mentioned prior art, the object of the prese...
