Abstract/Additional Information
This paper discusses the deficiencies in the earth embankment which led to the replacement of the dam, and describes several innovative design features of the new RCC dam. Key design features discussed include: (1) construction of the steep (0.5H:1V) downstream RCC face, (2) the improved method of attaching a PVC liner to the upstream precast panel facing system, (3) the computerized monitoring and control system used to grout the foundation, and (4) the accelerated construction of the dam which required eleven separate contracts.
