A high-seismic measures embankment dam and construction method

The invention discloses an aseismatic structure of a high earth-rock dam and a construction method thereof, and an aseismatic structure is constituted by steel bars, geogrids, stainless steel meshes, precast concrete anchoring sections and geogrid wrapping sections. In rockfill in an upstream dam shell and a downstream dam shell within the range from the dam top to 1/5-1/4 of the height of the dam, a layer of the steel bars is laid every three layers of the rockfill according to the number of the compacted layers of the rockfill material, asphalt is further top-poured for performing anti-rusting treatment, one end of each steel bar is fixedly connected with the precast concrete anchoring section and the other end of each steel bar is hinged with the stainless steel mesh on the dam surface; and the geogrid is laid on the rockfill in each layer after compaction, and each geogrid is reserved on the dam surface for being turned and rolled onto the rockfill of the upper layer after roller compaction for forming the geogrid wrapping section; and the steel bars on the top surface of a core wall penetrate through the whole rockfill for connecting the stainless steel meshes on the upstream dam surface and the downstream dam surface. The aseismatic structure of the high earth-rock dam absorbs the advantages of flexible material and rigid material in the aseismatic aspect, the aseismatic performance is good, the construction is convenient, the construction progress is not affected, the size of a dam body is not increased and the aseismatic structure of the high earth-rock dam is economic and practical.
