The bottom plate can be made of patterned steel plate, and the side plates can be made of acrylic plate. The specific dimensions of the horizontal groove 101 and the inclined groove 102 can be determined according to the needs. For example, the horizontal groove 101 can be 2m long, 50cm wide, and 40cm high on both side plates, while the inclined groove 102 can be 3m long, 50cm wide, and 40cm high on both side plates.

[0038] In addition, the chute device can further include a flat box 103 for receiving the ice and rock debris 9, the rear end of the flat box 103 being connected with the front end of the horizontal chute 101; the length of the bottom plate of the flat box 103 can be 2 m, the width can be 1.5 m, and the height of the two side plates can be 15 cm.

[0040] The positioning plate 201 can be a rectangular steel plate structure, which provides support and movement path for the material box 202; the ice and rock debris 9 is a mixture, which is filled by layering of gravel materials (for example, granite and limestone particles with diameters of 0.5-1 mm, 1-2 mm, 2-5 mm, 5-10 mm and 10-20 mm can be used, and the particles are sieved by a porous sieve to prepare well-graded gravel materials) and ice particles; the material box 202 is of an open-top structure, which facilitates the filling of the ice and rock debris 9; the baffle 202a at the front end of the material box 202 is of a openable and closable structure, which can be automatically opened when the material box 202 reaches the rear end of the inclined chute 102 at high speed, so that the ice and rock debris 9 can move to the inclined chute 102 at high speed.

[0041] The bottom of the inclined chute 102 and the positioning plate 201 are supported by lifting devices and can be adjusted in height by the lifting devices; of course, during the adjustment, the bottom plate of the horizontal chute 101 and the positioning plate 201 are always located on the same straight line. The lifting device can include a plurality of lifting racks 301, the top of the lifting rack 301 being connected with the inclined chute 102 or the positioning plate 201, and the bottom being connected with a moving seat 302 used for moving on the ground, so as to adjust the position of each lifting rack 301.

[0042] In addition, the test system further includes a particle imaging velocimetry device (PIV device for short), which includes high-speed cameras 401 arranged on the left and right sides of the horizontal chute 101.

[0044] In the specific test, the following steps can be performed:

[0045] S1, debugging PIV device: test the PIV device through the chute flow sliding test of small size ice-rock debris 9 to determine its accuracy.

[0046] S2, start the temperature changing device, preheat / precool the bottom plate of the inclined chute 102 to make the bottom plate reach the target temperature.

[0047] S3, load the material box 202 and the high-speed camera 401: after adjusting the angle of the inclined chute 102, the prepared material is filled in the material box 202 according to the set porosity ratio, and the filling mass is recorded, the material box 202 is loaded to the positioning plate 201, and the high-speed camera 401 is placed on both sides of the horizontal chute 101 respectively, which is used to shoot and analyze the internal velocity field and deformation characteristics of the ice-rock debris 9 in different motion stages along the inclined surface, and to shoot and analyze the motion characteristics of the horizontal section debris flow.

[0048] S4, adjust the inclination angle of the inclined chute 102 through the lifting device, and the initial speed provided by the power device needs to be adjusted and selected according to the model and the total mass of the material box 202.

[0049] S5, perform solid-fluid conversion flow sliding test: start the power device to make the ice-rock debris 9 break through the baffle 202a to flow and slide, and during the whole sliding process, the high-speed camera 401 tracks the dye in the ice-rock debris 9 to record the changes of the internal structure of the ice-rock debris 9 during the whole flow and sliding process.

[0050] S6, immediately after each flow and sliding test, the material collected in the flat box 103 is weighed again to calculate the mass of the melted water.

[0051] After the test, the collected images can be processed and analyzed by using open source software GeoPIV. Based on the processing of the texture structure and other information of a specific area in each adjacent two frames of objects, i.e. the PIV image subset, the displacement of the subset passing through the calculation area within the adjacent time step is calculated, and then the velocity vector field information of the debris flow in different areas and at different times can be obtained, and the velocity distribution characteristic curve of the debris flow from the bottom to the surface (along the depth change) at different times can be extracted. By analyzing the pictures taken by the high-speed camera 401 placed at different positions, the relative motion characteristics of particles at different depths of the ice-rock mixture material can be obtained, and the shear deformation law of the moving debris body can be obtained by analysis and summary. Finally, by studying the nonlinear or linear distribution law of the velocity distribution and the corresponding material characteristics (including gradation, ice content, motion speed, bottom plate temperature, melted water amount, etc.), the solid-fluid conversion motion drag reduction law of the ice-rock debris 9 from "solid sliding" to fluidized motion is revealed.

[0052] The above method is also a test method for simulating the solid-fluid conversion motion of high-speed ice-rock debris corresponding to the above test system.
