Description
Technical field
The soft rock that the utility model relates to a kind of subregion layout builds rock dam body, is applicable to Hydraulic and Hydro-Power Engineering.
Background technology
Early stage rock adopts dumped rockfill dam body, with the antiseepage such as wooden boards, steel facing.Because dam body filler adopts the construction method of throwing, generally not subregion.Along with the development of construction technique of earth and rock dam, rock introduces the concept of subregion from subregion earth and rockfill dam, and along with the development of computing technique, the zoning design of counter plate loose rock dam is also day by day perfect, the zoning design gradually standardization of rock.
In Hydraulic and Hydro-Power Engineering, when water retaining structure adopts Concrete Face Rockfill Dam, dam body should carry out subregion according to factors such as river valley orographic condition, material source, deformation properties, height of dam, construction and economic performances.Dam zoning should utilize building to excavate Jin Ba district as far as possible can use material source, and the water permeability in each district of enrockment dam body should increase from upstream toward downstream, and dam zoning should be conducive to Deformation control; And according to engineering experience, in order to improve dam body stress state and coordinate dam zoning distortion, then need the compatibility of deformation problem solving Concrete Face Rockfill Dam soft or hard rock.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, the soft rock providing a kind of subregion to arrange builds rock dam body, have improve dam body stress state, coordinate dam zoning distortion, structure is simple, easy construction, the feature such as safe and reliable.
The technical scheme that the utility model adopts is: the soft rock that a kind of subregion is arranged builds rock dam body, this dam body upstream side is followed successively by panel from outside to inside, bed course district and transition region I, upstream face base of dam place internal layer is upstream apron district, skin is Gai Chong district, upstream face base of dam periphery fissure has special bed course district, it is characterized in that: be provided with Transition Zone of Deformation in axis of dam position, the upstream side of Transition Zone of Deformation is with low compressibility, the rockfill area, upstream that the good upstream stockpile of grating fills, the downstream of Transition Zone of Deformation is the rockfill area, downstream of filling with soft rock material, Transition Zone of Deformation is by upstream stockpile and the soft rock material layering of rockfill area, downstream is overlapping fills, dam body bottommost is catchment.
Described Transition Zone of Deformation and the transition region II establishing 1 ~ 2m thick between rockfill area, downstream and catchment.
Described dam body downstream face is pitched work.
Stockpile every one deck filling-up thickness in described upstream is 80 ~ 90cm, and rockfill area, downstream soft rock material every layer of filling-up thickness is 30 ~ 40cm.
The beneficial effects of the utility model are: 1, the utility model is that the soft rock that a kind of subregion is arranged builds rock dam body, and rockfill area, dam body downstream adopts soft rock to fill, and can effectively utilize building excavated material, remarkable in economical benefits; 2, in the utility model, between rockfill area, upstream and downstream, Transition Zone of Deformation is set, namely adopts that upstream and downstream stockpiles is overlapping to be filled, have improve dam body stress state, coordinate dam zoning distortion, structure is simple, easy construction, the feature such as safe and reliable.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model.
Detailed description of the invention
As shown in Figure 1, the soft rock that a kind of subregion of the present embodiment is arranged builds rock dam body, this Rockfill Dam is filled by rockfill area, upstream 4 and rockfill area, downstream 6 and forms, and stockpile every one deck filling-up thickness in upstream is 80 ~ 90cm, and soft rock material every layer of filling-up thickness is generally 30 ~ 40cm; Between rockfill area, upstream and downstream, the overlapping soft or hard rock that fills of layering forms Transition Zone of Deformation 5 (i.e. axis of dam position), for improving dam body stress figure, coordinating dam zoning distortion, fill the concrete ratio of soft or hard rock, scope determines according to field roll compaction test, dam body stress-strain analysis; In Transition Zone of Deformation, the bottommost of rockfill area, downstream arranges catchment 8, piles between stone-laying district 6 be provided with the thick transition region II of 1 ~ 2m 7 (soft or hard rock Transition Materials) in this catchment and Transition Zone of Deformation 5, downstream.
The dam material that rockfill area, upstream 4 adopts low compressibility, grating good fills, and is the main support body bearing horizontal load of rock; The upstream side of this rockfill area, upstream is equipped with transition region I 3, bed course district 2, panel 1 from inside to outside successively, under upstream face base of dam periphery fissure, arrange special bed course district 12, and lays upstream apron district 11 and Gai Chong district 10 successively in the outside of upstream face base of dam panel 1.
Rockfill area, downstream 6 adopts soft rock to fill under the prerequisite ensureing dam stabilization, and the downstream face in rockfill area, downstream 6 lays pitched work 9.
The present embodiment is for guaranteeing that deformation of concrete face rockfill dam is even, and the elastic modulus difference of upstream and downstream stockpile should control between 2 ~ 5 times.
