Description
Technical Field
The invention relates to the technical field of hydraulic and hydroelectric engineering, in particular to an ultra-high rock-fill dam structure suitable for hydraulic and hydroelectric engineering.
Background
The rock-fill dam is a dam built by filling stone and matching with impervious body. It is one kind of earth-rock dam. The dam has the advantages of fully utilizing local natural materials, adapting to different geological conditions, being simple in construction method, good in earthquake resistance and the like. The method has the defect that a diversion and flood discharge building is generally required to be constructed outside the dam. The dam body consists of rock-fill and seepage-proofing bodies, wherein the rock-fill accounts for more than 50% of the volume of the dam, and the earth-rock dam is formed by throwing and filling or rolling. The rock-fill dam design is basically similar to the earth dam design, including stability analysis, seepage calculation, subsidence calculation, dam body detail structure design and the like. The stress strain calculation is carried out on the high rock-fill dam by adopting a finite element method so as to know the stress and deformation condition of the dam body and whether a region generating tension and cracks exists or not. And the stability calculation of the dam body can adopt an arc method and a broken line method according to the dam body. When the rock-fill bodies on two sides are thicker, the stable safety coefficient of the rock-fill bodies can be directly obtained by using the ratio of the internal friction angle of the rock-fill bodies to the slope angle of the rock-fill bodies. In the seismic area, the seismic load should be accounted for. The subsidence of rock-fill dams, when stacked or flung, is difficult to determine computationally. According to experience, a casting and filling method is used for building the dam, and the subsidence amount after completion can reach 1% -2% of the height of the dam. The vibration rolling method is adopted to build the dam, and after the construction is finished, the settlement amount of the rock-fill is small. If the concrete core wall is used, stress transfer can be generated when the concrete core wall is solidified, the core wall is caused to arch, horizontal cracks are generated, such as reinforced concrete panels or asphalt concrete inclined walls are adopted, excessive panel subsidence is easily caused at the position of a steep bank after water storage, water stopping damage is caused, besides the phenomenon that the concrete core wall is used for carrying out calculation and analysis through a finite element method, measures are taken structurally, and the cracks are prevented. However, in the long-term use process of the current rock-fill dam, the panel layer is extremely easy to damage under the flapping of tidal water, the service life of the rock-fill dam is reduced, after the panel is flapped and damaged, the seepage resistance of the rock-fill dam is reduced, so that water is easy to infiltrate into the inside of the rock-fill dam body, the overall stability of the rock-fill dam is reduced, the normal use of the rock-fill dam is affected, and potential safety hazards exist.
