Anti-seismic measure and construction method of a high earth-rock dam

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to an anti-seismic measure for a high earth-rock dam and a construction method thereof. Background technique [0002] 80% of my country's water energy resources are concentrated in the west. With the development of social economy and the development of water energy resources, a large number of high dams will be built in these places to develop and utilize these water energy resources. Earth-rock dams have the advantages of easy material selection, low cost, simple structure, and good seismic performance, and have been widely used in the world. In recent years, with the in-depth research on the properties of earth-rock materials and the progress of construction technology, earth-rock dams have become one of the mainstream dam types in high dam construction in the world. However, due to the limitation of the spatial distribution of water resources, h...
