Embodiment 1
[0034] Such as figure 1 As shown, the present invention provides a water movement simulation device for a rock-soil slope with root stone structure, including:
[0035] Box 1;
[0036] The top surface of the box 1 is a slope, and the slope of the slope is 30 degrees;
[0037] The bottom plate, two ends and one side of the box are cement exterior walls, the other side of the box is a glass observation wall, and the two ends are respectively located at the upper and lower ends of the slope; preferably, the bottom of the box 1 , the upper retaining wall, the lower retaining wall and one side are all made of reinforced concrete structure, and the other side of the box body 1 is made of tempered glass retaining wall, which is strong enough to ensure the load bearing of the retaining wall. Observation window for vertical movement of moisture in soil profile
[0038] The box body 1 is sequentially segmented from the highest end to the lowest end, and the depth of each segment grad...
Embodiment 2
[0049] refer to figure 2 , the present invention also provides a kind of experiment method that utilizes the water movement simulation device on the rock-soil mass slope surface containing root stone structure that embodiment 1 provides, comprising:
[0050] S1: Rainfall events that simulate moisture movement on slopes, including:
[0051] Simulation of artificial rainfall events according to different rainfall amounts;
[0052] Use the soil moisture probe to automatically monitor the water content of the backfill soil layer;
[0053] collecting the effluent from the backfill soil layer;
[0054] According to the monitored water content and the collected effluent, draw the dynamic change diagram of rock and soil moisture on the slope and the dynamic diagram of the effluent under artificial rainfall events corresponding to different rainfall, preferably the rainfall is 5mm / h, 20mm / h and 50mm / h;
[0055] S2: Combined with tracer experiments, simulate the preferential flow of...
