“…Embankment dam with earth core wall (core wall dam) originates from the homogeneous earth dam and its derivative earth dam [1] and has gradually become the most common type of embankment dam, especially high embankment dam. Some 300-meter-high embankment dam under planning, design, and construction such as Nurek Dam (300 m), Nuozhadu Dam (261.5 m), Lianghekou Dam (295 m), Shuangjiangkou dam (312 m), and RM Dam (315 m) are all core wall dams [2][3][4][5][6][7][8][9].…”

With the development of a 300 m high dam and large reservoir construction, the emergency drawdown capacity of cascade reservoirs, especially high dams, has become a hot issue of concern to all sectors of society while giving play to huge comprehensive benefits. Based on a thorough investigation of the current situation of drawdown facilities for high dams and large reservoirs with a height of 200 m or more in the world, this paper finds that drawdown facilities currently face difficulties such as insufficient drawdown capacity, poor safety and stability of high head structures, extremely high lift hoisting equipment, and high difficulty in high head water seal technology. It is pointed out that the key technologies that need to be urgently addressed for a deep drawdown of high dams and large reservoirs are the pressure-bearing capacity of gates and the capacity limit of hoists. As a result, the elevation of the bottom tunnel of the drawdown building cannot be arranged and the orifice is limited, and the drawdown depth and discharge capacity are limited.
