Description

[0001] This application is a divisional application of a patent application entitled "Moisture Movement Simulation Device and Experimental Method for Rock and Soil Slope with Root Stone Structure". The filing date of the original application is August 14, 2020. technical field [0002] The invention relates to the technical field of soil slope hydrology, in particular to a water movement simulation device and an experimental method on a rock-soil body slope with root stone structure. Background technique [0003] On slopes covered by vegetation for many years, plant root pores are the main biological factors that form soil preferential flow channels, and the strong spatial heterogeneity of gravel distribution and morphology increases the complexity of soil water movement processes. The impact of traditional soil hydrology research paradigms on root-stone structure is still insufficient, but the water movement process of root-bearing rock and soil is complex, which is the main...
