Abstract

The aim of researching the current hydrogeological state of the territory adjacent to the TsknetiSamadlo highway is to present such anti-landslide measures with the help of which normal operating conditions of the highway should be created. The study area is located on the northern side of the southeastern fork of the Trialeti Range, from the slopes of which many deep erosional ravines originate, filled in the spring-summer period with water that flows into the gorge of the r. Vere. The river is the main basis of erosion of the study area. To carry out hydrogeological studies, two water samples were taken - the water found on the landslide slope, which flowed along the surface of the bare slope, and a small amount of ground water from under the slope. The data of the chemical analysis of waters showed that these two samples are identical in chemical composition. The results of the total mineralization correspond to M = 1.9 g / l. Consequently, the water is not suitable for drinking, as it belongs to the category of slightly saline waters and is classified as sulphate-hydrocarbonate calcium-sodium. In addition to water samples along the road, one soil sample was taken to determine the degree of soil contamination. In the extract of a soil sample, the indicator of total mineralization is slightly increased (M = 0.3 g / l), according to its chemical composition, it is classified as hydrocarbonate-sulphate sodium-calcium. With regard to the anti-landslide measures proposed for the investigated area, the main one is the regulation of surface water flows using a system of spillways and drainages, which requires an accurate calculation of the height and steepness of slopes, in addition, maximum preservation of vegetation cover on deluvial slopes is required.
