Embodiment 1
[0044] Taking the field test of the gravity erosion process of the loess gully slope as an example, the specific steps of the device implementation for establishing the field test of the gully slope gravity erosion process are explained. The experiment was carried out in the Liudaogou watershed of Shenmu County on the Loess Plateau.
[0045] Step 1: Preliminary arrangement of the terrain
[0046] The generalized slope surface is designed according to the typical landform features of Huangtugou slope. The projected dimensions of the model along the slope and perpendicular to the slope are 300cm and 400cm, respectively. The entire slope is composed of a gentle slope of 3° and a steep slope of 60°~80°, and the height of the steep slope is 1.5m. The generalized slope surface is preliminarily sorted out on the gully slope that is prone to gravity erosion. Step 2: Build a mobile laboratory
[0047] Build and assemble the field laboratory 4 on site. The test chamber is 8m long and 5m w...
