THE ENGINEERING DECISIONS FOR MITIGATION OF DAMAGES IN LANDSLIDE HAZARDOUS REGIONS OF UZBEKISTAN

Uzbekistan is subject to several types of disasters caused by natural hazards, such as earthquakes, droughts, floods, landslides, and man-made, including transport accidents and emergencies. The mountainous and foothill areas of the country are also subject to significant risk of landslides. At the same time, over the past 80 years, more than 2,600 cases of large mudslide have been reported. Protection of the population and territories from emergency situations associated with landslide, flood, mudflow and avalanche events is one of the priority tasks in the field of safety. The main factor in provoking a landslide is its waterlogging. In this regard, in this paper, in order to eliminate a possible catastrophe, effective engineering solutions are proposed for drainage facilities, blocking the path of surface and groundwater to the landslide massif. Surface drainage and deep drainage systems are used for drainage. Surface waters are diverted by ditches, underground waters - by tunnels or horizontal wells. Despite the high cost of these activities, the cost of building drainage systems is much lower than the cost of eliminating the consequences of a possible disaster. Drainage systems are designed in such a way as to collect the maximum possible flow of surface water from the area and take it to the places of possible discharge or to treatment facilities.
