FIELD: civil engineering; stabilization of deforming processes of earth-filled embankments. SUBSTANCE: landslide control structure for spread landslide has groups of pile foundation supports, supporting buttress members of frames, spacer beams and beam-type longitudinal members. Supporting members of buttress frames are made in the form of double-broken channel-section beams installed in definite manner in relation to groups of pile foundation supports. Free end of horizontal member is connected with pilework block. Middle part of curved beams and inclined member are made with vertex of bend at angle within 90≅α≅ 120with vertex directed downwards towards plane of sliding. Beam-type longitudinal members are attached to every two adjacent curved beams of channel section thus forming pockets filled with counterbank filler of draining material. Landslide mass of earth is terraced. Terracing with redistribution of landslide mass of earth is performed according to equivalent counterbank profile for embankments corrected with respect to changing action of tangential forces over cross-section of landslide. EFFECT: high efficiency. 2 cl, 3 dwg |
