Description
Technical field
The present invention relates to a kind of dam facing point type means of defence and structure applied to high earth and rockfill dam antidetonation reinforcement, belong to water conservancy
Hydropower industry earth and rockfill dam anti-seismic technology field.
Background technology
Extensively using earth and rockfill dam structure dash in Hydraulic and Hydro-Power Engineering, and frequently area must carry out soil in seismic activity
Masonry dam Aseismic Design.At present, in the high earth and rockfill dam in western China（Core wall dam, face dam）Often implement anti-in dam crest near zone
Reinforcement measure is shaken, prevents that dam slope slides during earthquake.
By literature search, high earth and rockfill dam dam crest antidetonation reinforcement measure nearby has three classes：The first kind is sash beam type formula antidetonation
Reinforcement technology, such as Tajikistan within the border exert lek core wall rockfill dam, China Luding power station engineering.Equations of The Second Kind is geotechnique
Grid antidetonation reinforcement technology, such as China's smelting strangle rockfill dam with asphalt concrete core, Pubugou Project core-wall core wall rockfill dam, the long sill may heart
The engineerings such as wall rock-fill dams.3rd class is stainless reinforcing bar material antidetonation reinforcement technology, such as China's Nuozhadu earth core rockfill dam, seedling tail core-wall
The Hydropower Projects such as rock-fill dams.The dam facing safeguard structure processing matched with above-mentioned antidetonation reinforcement measure can be divided into：Dam facing is anyhow
Sash beam, GSZ termination are built boulder protection, dam facing band steel net by laying bricks or stones and are connected with stainless reinforcing bar material in dam body after reversely wrapping up.
Earth and rockfill dam belongs to flexible dam, and dam body can produce continuous deformation, the high soil in part during work progress and impounding and operation
Masonry dam dam deformation is up to 3m or so.Thus, the earth and rockfill dam dam facing of reinforcement protection occur during with dam deformation dislocation, it is grand
Rise etc. phenomenon.If dam facing is using band steel net, the rigid web frame such as sash beam can produce destruction or protuberance failure conditions anyhow.
Geo-grid material can be with native stone compatibility of deformation, but GSZ is typically made by high molecular polymer, its
Durability is poor, and it is damaged that the high impact forces during native stone rolling and placement may occur GSZ；Grid material is in dam facing
Outside loose stone is not wrapped up, and antidetonation effect will be combined with dam facing to be reduced.
The content of the invention
It is an object of the present invention to provide a kind of dam facing point type means of defence and knot applied to high earth and rockfill dam antidetonation reinforcement
Structure, to overcome existing high Earth and Rockfill Dam to offend and disobey with rude remarks the shortcoming for the dam facing rigid mesh malformation inaccurate coordination for shaking reinforcement.
The technical proposal of the invention is realized in this way：
A kind of dam facing point type means of defence applied to high earth and rockfill dam antidetonation reinforcement of the present invention, the dam body of the high earth and rockfill dam by
Earth and stone material accumulation is formed, and the antidetonation reinforcement area upstream and downstream of dam body is domatic to be reinforced by loose stone, is added in dam body provided with multiple-layer horizontal
Muscle；This method is to be uniformly distributed one group of cross or M shape steel member, steel member and dam body in domatic loose stone outer surface
Interior horizontal reinforcement welding, limits dam facing deformation or sliding that dam body is produced in earthquake, so as to improve native stone by steel member
The shock resistance on dam；Specific construction step is as follows：Dam embankment is carried out first, and dam facing loose stone should be reserved when filling dam body
Region is filled, using placement in layers method, 1-3 layers of earth and stone material is often filled and just lays one layer of horizontal reinforcement, level on earth and stone material surface
Reinforcement should reserve the length overlapped with dam facing steel member；Then in domatic some cross of placement of upstream and downstream or rice word of dam body
Shape steel member, and the horizontal reinforcement in steel member and dam body is welded；Build loose stone by laying bricks or stones between steel member and dam body again and complete
Into dam facing finishing.
In preceding method, the dam body carries out making by the way of layered rolling, and the thickness t of each rolling layers is 0.6
~0.8m；It is 0.6~2.4m that the interlamellar spacing h between one layer of horizontal reinforcement, horizontal reinforcement is laid between every 1~3 rolling layers.
In preceding method, the plane of cross or M shape the steel member formation is domatic parallel flat with the upstream and downstream of dam body
Together, the pad of cross or M shape steel member and the flat reinforcement of water in dam is no less than at 3 points.
Above and below a kind of anti-seismic structure of the high earth and rockfill dam of the invention formed according to the above method, including dam body, dam body
Trip is domatic, and domatic to be provided with laid dry rock layers, laid dry rock layers, which are externally provided with cross or M shape steel member, dam body, is provided with multilayer
Horizontal reinforcement, cross or M shape steel member are welded with horizontal reinforcement.
In aforementioned structure, cross or the M shape steel member uses band steel, I-steel or the similar platypelloid type type of channel-section steel
Steel is welded；The cross-sectional width b of band steel, I-steel or channel-section steel is not less than 100mm.
In aforementioned structure, cross or the M shape steel member include the domatic horizontal member of parallel dam body upstream and downstream and
The domatic diagonal of parallel dam body upstream and downstream, the length L1 of horizontal member is 1~5m, and the length L2 of diagonal is 2~6m.
By adopting the above-described technical solution, the present invention is compared with prior art, cause present invention, avoiding dam deformation
The destruction of mask muscle material or the Problem of Failure such as protuberance, strengthen muscle material and mask muscle material in dam body combines antidetonation effect.
