Abstract
The present invention includes an anti-ice pushing/pulling device installed on the slope of an earth-rock dam and an ice thrust calculation method. The device is arranged in a groove formed on the surface of an upstream slope of the earth-rock dam in the winter water level change area, and includes an upper concrete slab and a lower concrete slab hinged by means of a rotating shaft structure, where the rotating shaft structure is located at the end of the groove in the dam slope far away from the dam crest; a jack is arranged between the two concrete slabs to adjust the flip angle of the upper concrete slab; a plurality of rectangular grooves are formed on the surface of the upper concrete slab, and a combined structure formed by splicing concrete blocks is arranged in the rectangular grooves; and holes are formed on the concrete blocks.
