1 INTRODUCTION
CFRD (Concrete faced rock-fill dam) or CFGD (Concrete faced gravel-fill dam) have competitiveness in aspects of economy and safety because seepage instability is primarily prevented by watertight design using concrete face slabs. This seepage control does not allow pore water pressures to be accumulated in a dam and provides many advantages, including simpler design and construction, shorter construction periods, and enhanced stability in case of earthquakes.
