Embodiment 2

[0041] A kind of experimental method that adopts above-mentioned device to carry out the anti-erosion research of vegetation slope, this method comprises the following steps:

[0042] Step 1: Construct a pseudo-natural slope rock mass model 10: Use a 3D laser scanner to collect the rock mass structure and terrain data of the slope to be restored, scale it down to a vertical projection area of ​​less than 100cm×100cm, and make it according to the reduced 3D map, etc. Comparing the mold, mix coarse and medium-grained quartz sand, gypsum, sodium citrate and water to a mortar state, pour it into the prefabricated mold and vibrate it, and then solidify and demould, and the pseudo-natural slope rock is completed. Construction of phantom 10;

[0043] Step 2: Fix the constructed pseudo-natural slope rock mass model 10 on the bottom of the uncovered substrate box 2;

[0044] Step 3: Construct the soil substrate layer 11: Use natural soil or the soil medium applying the slope vegetatio...

Abstract

The invention provides a scour resistance research device for vegetation slopes comprising a hydraulic jacking slope model body. At least one uncovered substrate box is slidably connected to the liftable slope surface of the hydraulic jacking slope model body. The uncovered substrate box comprises a base plate used for placing a simulation natural slope rock mass model. One side panel, close to arotating side of the hydraulic jacking slope model body, of the uncovered substrate box is a detachable sliding side plate. One side of the hydraulic jacking slope model body is placed with a muddy water collection box matched with the uncovered substrate box. An artificial rainfall device is hung on the upper part of the uncovered substrate box. The width of the detachable sliding side plate is matched with the height of a soil substrate layer. The scour resistance research device and the experimental method for vegetation slopes provided by the invention can comprehensively and quantitatively evaluate the scour resistance of the vegetation slopes, and it has important theoretical research and technical guidance values for slope vegetation recovery.

Description

technical field [0001] The invention relates to the technical field of slopes, in particular to a research device and an experimental method for the erosion resistance of vegetation slopes. Background technique [0002] my country's mountainous area accounts for 33.3% of the country's land area, and landslides and geological disasters occur frequently. Rainfall is one of the common inducing factors of landslides. Studies have shown that more than 60% of slope instability is caused by rainfall. In recent years, heavy rainfall and torrential rain have hit some areas of our country many times, causing many geological disasters and seriously threatening the safety of people's lives and properties. A large number of exposed engineering slopes have been formed in my country's engineering construction, which has destroyed the ecological landscape of the region, and also caused a large amount of soil loss and degradation. From the current research on the application of plant slop...
