Abstract: The basic earthquake intensity in the dam site area of Karot Hydropower Station in Pakistan is VIII. With maximum height of asphalt concrete core wall of 95.5m, it is the highest asphalt concrete core rockfill dam that is filled by weak rock under construction now in the world. The filling material mainly adopted excavated rock material from spillway and water diversion part, and the lithology was sandstone and muddy siltstone with uniaxial saturated compressive strength of 8~25 MPa，which is relatively weak rock-weak rock. Considering the high earthquake intensity, we introduce the design of Karot asphalt concrete core rockfill dam in the aspects of rational use of soft rock, stability of dam slope, deformation control of dam body, seepage control and seismic structural measures，and the results can provide references for construction.
