Description
Technical field
The present invention relates to hydro science dam field of engineering technology, more particularly to a kind of buttress type duplex face dam and
The method for improving the maintenanceability of panel.
Background technology
Face dam dam type because with to Dam Site topographic and geologic condition strong adaptability, good economy performance, it is safe and reliable the characteristics of,
It is rapidly developed in China, but part face dam high built in recent years occurs in that dam deformation is bigger than predicted value, panel
The problems such as there is extruding destruction, crack, big embankment seepage amount.These problems are attributed to three aspects：One is big dam deformation；Two are
The seepage control system such as panel destructible, destruction cause embankment seepage amount big, it is understood that there may be the potential safety hazard of seepage stability；Three is to tie up
Repairing property is poor, and lower panels maintenance is difficult, runs into extreme operating condition problem and more protrudes.Thus at present to 250m grades or panel higher
The security presence on dam is queried.
As China's economic development and the public, government significantly improve to safety requirements, to large and medium water power station engineering
Water retaining structure proposes the requirement that the extreme operating conditions such as macroseism are not fallen, design conditions can be used normally after repairing.The built 70m of China
Above face dam high does not overhaul the condition of base impervious system all.The presence of these problems, constrains the country to building 250
The decision-making of ~ 300m ultra-high concrete panel rock-fill dams.
When usual face dam high or superelevation face dam are designed, mostly from dam zoning, fill standard, joint seal, construction
The aspect research such as step, proposes to reduce dam deformation, improves the related measure of panel stress and control joint displacement.But these
Measure all cannot more effectively solve the technical problem existing for superelevation rock at present.
The content of the invention
In order to overcome face dam panel high in the prior art long, deform larger；Maintenanceability is poor, and lower panels maintenance is tired
Difficult defect, a kind of side of the maintenanceability it is an object of the invention to propose buttress type duplex face dam and raising panel
Method, concrete buttress structure is set by face dam bottom, the maintenanceability of profundal zone panel is improved so as to reach, improves super
High CFRD stress and deformations of concrete face slab and the purpose of dam deformation.
To realize above-mentioned technical purpose, the present invention is adopted the following technical scheme that and is achieved:
A kind of buttress type duplex face dam, including concrete slab, bedding material, the upper mistake set gradually by upstream to downstream
Cross material, upstream rockfill area, downstream rockfill area；In the concrete slab bottom, concrete buttress structure is set；The concrete
The upstream side of buttress structure sets Gai Chong areas, and downstream sets lower Transition Materials；The downstream of the lower Transition Materials is upstream enrockment
The bottom in area.
Preferably, the concrete buttress structure includes a lower flat portion；Prolonged upwardly by the upper table of the lower flat portion
The vertical portion stretched.
Preferably, the form of fracture of the vertical portion uses trapezoidal cross-section.
Preferably, gallery is overhauled in the monitoring that is internally provided with of the vertical portion.
Preferably, the vertical portion has a downstream outside wall surface；The upper table of the downstream outside wall surface and the lower flat portion
Multiple ribs are provided between face.
Preferably, the vertical portion has a downstream outside wall surface；The connection of the downstream outside wall surface and the lower flat portion
Place is provided with lead angle.
Preferably, the lower flat portion has a upstream-side end surface and a downstream-side end surface, and the vertical portion is near described
Upstream-side end surface is set.
Preferably, the upper Transition Materials are connected with the lower Transition Materials.
Preferably, the concrete buttress structure upstream slope ratio is 1：M, m are 1: 0~0.3；Downstream slope ratio is 1：N, n are
1:0.1~0.3。
Another object of the present invention, there is provided a kind of method of the maintenanceability of raising panel, in the upstream of concrete slab
The bottom of side sets concrete buttress structure；In the upstream side construction Gai Chong areas of concrete buttress structure；Helped in the concrete
The downstream of wall construction sets lower Transition Materials；The Gai Chong areas, the concrete buttress structure and lower Transition Materials are filled should be with high
Cheng Pingqi is filled.
Beneficial effects of the present invention：
The present invention is additionally arranged the concrete positioned at riverbed position concrete slab upstream side on the basis of conventional concrete panel
Buttress structure, instead of profundal zone panel, reduces panel length；And part stockpile is instead of, so as to improve profundal zone face
The maintenanceability of plate, improvement superelevation rock stress and deformations of concrete face slab and dam deformation, are face dam high or superelevation panel
The construction on dam provides foundation, especially 300m grade high CFRD；For the development of superelevation face dam provides support, promote super
High concrete panel rock-fill dams technological progress, is that the research of superelevation dam is accumulated experience.
