FIELD: construction.
SUBSTANCE: ground dam erected on weak bases in the regions with high seismic activity, includes the curved with convexity toward the upstream aperture the orifice 2 made of the viscoplastic material, formed with bulges in the form of local bosses 4 in zones of change of the aperture curvature 2, the concrete gallery 3 with the acquis in the top and impervious element 6 in the base 7. The lower part of the orifice 2 is formed as a closed shell 5 enclosing the concrete gallery 3 and conjugate to the impervious element 6 in the base 7. The concrete gallery 3 in the cross section is formed as a Reuleaux triangle. Also one of the corners of Reuleaux triangle is located in the top acquis part of the gallery. Orifice material in bosses has greater fluidity than in other parts of the orifice.
EFFECT: improved reliability of the ground dam at high seismic and static loads.
