Yulong Kashi water conservancy project is located in the high mountain and gorge area with steep bank slope. The basic intensity of site seismic is Ⅷ, and the seismic fortification intensity of dam is Ⅸ. It is a 230 m high earth-rock dam in the mountainous-valley reach where is cold and has strong earthquake. According to the construction conditions of earth-rock dams in the project area, the present situation of high earth- rock dams in strong earthquake areas at home and abroad is studied in detail. Three types of earth-rock dams are determined for comparison and selection, and the feasibility analysis is carried out one by one. Finally, the concrete face rockfill dam is selected as the recommended dam type. At the same time, the difficulties in dam design and the specific direction of scientific and experimental research are pointed out.
