The invention discloses a jointed development loess body infiltration test device and a test method. The device comprises an infiltration main device, an opening measurement system, a rainfall system,a water flow collection system and a moisture field test system; the opening measurement system is connected with the infiltration main device; the rainfall system and the water flow collection system are respectively communicated with the infiltration main device, and the moisture field test system is connected with the infiltration main device; two soil samples are arranged in the infiltrationmain device; one soil sample is fixed, and the opening degree of the jointed development loess body is measured by adjusting the movement of the other soil sample; a loess joint opening part is communicated through the rainfall system, and the infiltration condition of rainwater to the jointed development loess body is tested. According to the method, the influence of the opening degree on the infiltration of the jointed development loess body and the moisture field change process is quantitatively measured while the initial structure state of the soil body is not disturbed as much as possible.
Description
technical field [0001] The invention belongs to the technical field of rock-soil model test equipment, and discloses a test device for the infiltration of loess body with developed joints and a test method for the dynamic evolution of the infiltration water field. Background technique [0002] Loess joints are generally developed in loess, and loess joints are the dominant channel for water infiltration. During rainfall infiltration, due to the existence of matric suction in loess due to the development of joints, the water content in the soil changes and migrates, and the change of water content leads to changes in soil structure and properties. In severe cases, collapsible deformation may occur, directly causing damage to the foundation, and further changing the properties of the soil, and the cycle goes on and on, seriously affecting the construction of roadbed engineering, water conservancy engineering, and municipal engineering. These projects all involve the dynamic ch...
