Optimization of Anti-Seepage System for an Asphalt Concrete Core Rockfill Dam on a Deep Overburden Foundation
Seepage control is the key to building dams and reservoirs on deep overburden foundation. A reasonable seepage control scheme can not only effectively reduce the leakage in the reservoir area, but also help reduce the project investment. Taking an asphalt concrete core rockfill dam on a deep overburden foundation as an example, according to the topographic and geological characteristics of the dam site area and the seepage control scheme, a three-dimensional finite element model for dam seepage analysis was established. The saturated unsaturated seepage theory was used to calculate and analyze the seepage field, seepage flow and seepage gradient of the reservoir area under the design seepage control scheme, and the design seepage control scheme is optimized by changing the depth and length of the anti-seepage curtain. The results show that the curtain depth at the right bank dam foundation, left bank dam abutment and right bank dam abutment should be shortened by 10 m, and the curtain length of the right bank scheme should be extended by about 50 m. The optimized seepage control scheme can not only effectively control the leakage in the reservoir area, but also reduce the construction difficulty and project cost.
