Experimental research on the determination of the filtration characteristic on the base of low-pressure hydraulic engineering constructions on complex multi-layer ground

In this study, the issue of studying the filtration flow characteristics of hydraulic engineering constructions designed by building a hydrodynamic grid for the filtration flow area using the method of electrohydrodynamic similarity is considered. Given there is complexity and diversity of filtration deformation problems in base of hydraulic engineering constructions, we conduct experimental studies to determine the filtration flow characteristics in base of low-pressure hydraulic engineering constructions in a special model to determine the overall picture and qualitative assessment of these processes. Before observing the filtration deformation processes in the construction soil, the filtration coefficients of the soils in the soil were determined using the Darcy device. The purpose of determining the filtration coefficients of soils is the importance of using the value obtained in the laboratory under experimental work. Based on the experimental studies, graphs of the average filtration flow rate and specific flow rate depending on the water pressure were constructed. The theoretical results obtained were compared with existing analytical methods.
