Purpose: to develop the technology for accumulating groundwater flow, taking into account the rheological soil properties in the system of accumulating precipitation for expanding reclamation systems.
Materials and methods. With the help of an underground dam, the conditions for accumulating groundwater flow are created, taking into account the rheological soil properties in the system of accumulating precipitation for expanding reclamation systems. The studies were performed using the midas GTS NX software package. Mathematical modeling was performed in the wxMaxima software package.
Results. A set of technical devices combined into a technological system, intended for ensuring reliable accumulation of precipitation flow in the autumn-winter period and water withdrawal in the required volume, including dry periods of the year, in mountain river valleys with periodically intermittent watercourse has been developed. The technological scheme includes the construction of an impermeable underground dam in the cross section of the river valley, completely covering the aquifer in terms of power and width and forming the main underground reservoir. The regularities of the stress-strain state of the soil mass in time under the loads, including hydrostatic ones, are obtained at upstream water levels in the range from minus 8.19 to minus 1.18 m and downstream water levels from minus 7.93 to minus 6.68 m. It has been determined that the displacement of the underground dam foundation depends on pressure in the upstream of dam: the greater the pressure, the greater the displacement of its foundation, and with an increase in pressure by 4 times, the displacement of the foundation increases by 5.5 times.
Conclusions. The proposed technology of groundwater flow accumulation under conditions of water resources deficit, based on the system of regulation of an underground dam with lifting and transport equipment, is designed to guarantee the accumulation of natural waters and their use in irrigation systems.
