Description
Technical field
This utility model is related to hydro science dam construction technique field, more particularly to a kind of reduction panel stress strain level
Rock.
Background technology
Rock dam type have to Dam Site topographic and geologic condition strong adaptability, economical excellent, safe and reliable the characteristics of,
It is rapidly developed in China.Current CFRD is built dam level and has reached 200m (wherein water cloth a strip of land between hills most dams
High 233m), the face dam of several 250m～300m levels is just among design studies.The more consistent views of Ba Gong circle think at present：
100m level face dam technology maturations, dam body observational deformation is coincide substantially with Theoretical Calculation, safe and reliable；Although 200m face dams go out
Some problems are showed, but built engineering operation situation have shown, by taking appropriate engineering treatment operational excellence, be safety
's；For the face dam of 300m levels, due to some problems that theoretical research relatively lags behind and 200m level face dams occur, to dam
Body safety generates suspection.Design, construction and the operating experience of high face dam is summarized, superelevation rock has one very
Big problem is that panel stress strain is bigger than normal, causes face slab rupture, produces panel crack, cause embankment seepage amount big etc.
Series of problems.
When generally high face dam 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 effectively solve the technical problem existing for superelevation rock at present
Utility model content
In order to overcome in prior art, high face dam panel is long, and it is larger to bear water pressure, is also easy to produce extruding destruction and splits
The defect of seam, the purpose of this utility model are to propose a kind of rock for reducing panel stress strain level, by
Face dam bottom arranges concrete patch slope, so as to reduce panel length, effectively improves panel stress strain regime.
For realizing that above-mentioned technical purpose, this utility model are adopted the following technical scheme that and be achieved:
A kind of rock for reducing panel stress strain level, including the concrete set gradually by upstream to downstream
Panel, bedding material, Transition Materials, upstream rockfill area, downstream rockfill area, arrange concrete patch in the lower end of concrete slab upstream side
Slope, and the lower surface for pasting slope in concrete arranges concrete slab base.
Preferably, one end of concrete slab base extends laterally to the upstream outer that concrete pastes slope, concrete slab base
The other end extend laterally to the inside of upstream rockfill area.
Preferably, one end of the concrete slab base concrete paste slope upstream outer development length be 0.5～
2m.
Preferably, concrete patch 1 up stream slope ratio of slope is 1 with downstream slope than consistent：S, and the span of s be 1.3～
1.6.It is preferred that 1.4.
Preferably, concrete patch 1 thickness of slope is 0.05～0.1 times of head.It is preferred that 0.08 times of head.
Preferably, the concrete patch slope is highly less than 100m.
The beneficial effects of the utility model：
This utility model is additionally arranged bottom positioned at concrete slab upstream side on the basis of conventional concrete panel
Concrete pastes slope, replaces profundal zone panel, reduces panel length, so as to reduce panel stress strain level, reduces panel damage
With the probability in crack, the construction for high face dam or superelevation face dam provides foundation, especially the high panel heap of 300m levels
Masonry dam；Development for superelevation face dam provides support, fills up the blank of this area, promotes ultra-high concrete panel rock-fill dams technology
Progressive, it is that the research of superelevation dam is accumulated experience.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Embodiment 1
In order to overcome in prior art, high face dam panel is long, and it is larger to bear water pressure, is also easy to produce extruding destruction and splits
The defect of seam, this utility model provide a kind of rock of reduction panel stress strain level as described in Figure 1, including
The concrete slab 3 that set gradually by upstream to downstream, bedding material 4, Transition Materials 5, upstream rockfill area 6, downstream rockfill area 7,
The lower end of 3 upstream side of concrete slab arranges concrete patch slope 1, and the lower surface for pasting slope 1 in concrete arranges concrete floor
Seat 2.
This utility model arranges concrete patch slope 1 in the bottom of the upstream side of concrete slab 3, replaces profundal zone panel,
Reduce panel length, so as to reduce panel stress strain level, reduce the probability in panel damage and crack, be high face dam or
The construction of person's superelevation face dam provides foundation, is particularly suited for 300m level high CFRDs.
Embodiment 2
On the basis of embodiment 1, as described in Figure 1, one end of the concrete slab base 2 extends laterally to concrete patch
The upstream outer on slope 1, the other end of concrete slab base 2 extend laterally to the inside of upstream rockfill area 6.Slope 1 is pasted in concrete
Bottom arranges the basis that concrete slab base 2 pastes slope 1 as concrete, and concrete slab can reduce river valley ground as artificial basis
In the scrambling and geology of shape, the impact of the weak band in local, improves the support conditions of face dam, has vibrated buffering to dam body and has made
With.The thickness of the concrete slab base 2 meets code requirement less than 2m.One end of the concrete slab base 2 is in concrete
The development length of the upstream outer on patch slope 1 is 0.5～2m, by this extended distance, when concrete pastes slope 1 in construction
Wait, there is provided support, it is easier to which concrete pastes the construction on slope, it is also possible to reduce the stress born by concrete patch slope 1.
The concrete patch 1 up stream slope ratio of slope is 1 with downstream slope than consistent：S, and the span of s be 1.3～
1.6, preferably 1.4.Such ratio can fully meet the requirement for reducing ess-strain, while construction cost is not high yet, the duration
Also relatively short.
