FIELD: construction engineering. SUBSTANCE: method relates to compaction of slopes by tamping in erection of hydraulic engineering structures. According to method, strip of earth is compacted by tamping machine in upper part of projected slope in parallel to its horizontal longitudinal axis. After that, parallel trenches are dug out successively in direction from top to bottom of slope which are parallel to compacted strip of earth. Bottoms of trenches are compacted. Trenches are then backfilled layer by layer with compaction of earth by tamping machine. Trenches are dug out to depth which increases for each successive trench by depth compacted by tamping machine. Application of aforesaid method prevents horizontal shifting of earth together with reduction of labour-intensity. EFFECT: higher efficiency. 1 cl, 4 dwg
