Abstract
The utility model discloses a dam body sectioning structure of a concrete face rockfill dam with a large overburden depth. The dam body sectioning structure comprises a dam body, a transition layer section, a cushion layer section, a reinforced concrete face, a downstream revetment section, a dam body berm and a downstream ballast pressing section. The dam body consists of an upstream side primary enrockment section and a downstream side secondary enrockment section; the transition layer section, the cushion layer section and the reinforced concrete face are sequentially arranged along an upstream slope of the primary enrockment section, and the downstream revetment section and the dam body berm are sequentially arranged along a downstream slope of the secondary enrockment section; the downstream ballast pressing section is arranged at the position of a dam toe along the downstream side of the dam body. A boundary of the primary enrockment section and the secondary enrockment section consists of an oblique line segment and a straight line segment, the top end of the oblique line segment is positioned on the dam axis at the position of 3/4 dam height, the lower end of the oblique line segment extends to the downstream dam toe at a position 2m higher than the downstream maximum water level, the gradient of the oblique line segment is 1:0.6, and the straight line segment is a horizontal line which extends from the lower end of the oblique line segment to the downstream ballast pressing section. The dam body sectioning structure of the concrete face rockfill dam with the large overburden depth has the advantage that since the boundary of the primary enrockment section and the secondary enrockment section is moved to the downstream side of the dam body, stability of the dam is improved.
Description
Technical field
The utility model relates to dark covering layer rock dam body, especially relates to dark covering layer rock dam zoning three-dimensional-structure.
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 subregion not.Along with the development of construction technique of earth and rock dam, rock is introduced 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 gradually standardization of the zoning design of rock.But, along with the rockfill area, upstream (main rockfill area) of dam body, line of demarcation, rockfill area, downstream (inferior rockfill area) are from downstream toward upstream side shifting, the variation that the corresponding generation of dam body displacement stress is certain, and the most obvious with dam body settlement increase, dam body horizontal movement also increases to some extent.For high rock, will produce certain impact to dam body settlement and stress, stress and deformations of concrete face slab, seam displacement, what have the greatest impact is dam body settlement.
Summary of the invention
The utility model object is to provide a kind of dark covering layer rock dam zoning three-dimensional-structure.
For achieving the above object, the utility model is taked following technical proposals:
Dark covering layer rock described in the utility model dam zoning three-dimensional-structure, comprises the dam body being made up of the main rockfill area of upstream side and time rockfill area, downstream; Along the domatic transition zone district setting gradually, upstream, described main rockfill area, bed course district and steel concrete panel, the domatic downstream protection slope district setting gradually and dam body packway along downstream, described rockfill area; Be positioned at base of dam position along dam body downstream and be provided with ballast pressure slope district, downstream; The line of demarcation of Yu Ci rockfill area, described main rockfill area is made up of the oblique line section and the straightway that are positioned at dam body downstream, the top of described oblique line section is positioned on the axis of dam at height of dam 3/4 place, its lower end extend to apart from the bottom of dam, downstream higher than 2 meters of elevation places of downstream peak level, the gradient of oblique line section is 1:0.6, described straightway be from described oblique line section lower end downstream side extend to the horizon in ballast pressure slope district, described downstream; Downstream, described the rockfill area line of demarcation gradient domatic and described downstream protection slope district is 1:1.6; Be positioned at domatic fine coal gray area, loam bedding district, the rock ballast Gai Chong district of being disposed with of described steel concrete panel of base of dam position along dam body upstream side; The gradient in described fine coal gray area, loam bedding district equals the gradient of steel concrete panel, and the gradient in described rock ballast Gai Chong district is 1:2.5; Be provided with curtain grouting district in the bottom that is positioned at dam body upstream side impervious wall.
The utility model advantage is the line of demarcation of Yu Ci rockfill area, described main rockfill area to move to dam body downstream, and the gentle slope that the described marginal oblique line section gradient is made as to 1:0.6, has greatly reduced settlement stress, the distortion of panel stress and the displacement of seam of dam body like this.Be positioned at domatic fine coal gray area, loam bedding district and the rock ballast Gai Chong district of being disposed with of steel concrete panel of base of dam position along dam body upstream side; Be positioned at base of dam position along dam body downstream and be provided with ballast pressure slope district, downstream, rock ballast Gai Chong district, upstream and ballast pressure slope district, downstream can prevent that dam foundation earthquake liquefaction from can increase again dam stability; By main rockfill area being set in bottom, rockfill area, downstream, can comparatively fast reduce dam seepage line, ensure that dam body internal drainage is unobstructed, improve dam stable.
