Abstract:Due to the significant social influence and military value, the high dams with large reservoir are the primary target of terrorist attacks and local wars. The antiknock security problem of the cascaded hydroelectric power plant is more vital. Once a high dam in the cascade reservoir group is destroyed by the explosion, it may cause secondary flood disaster and chain reaction. In this work, those dams around the world attacked by explosions are reviewed, and the key scientific and technical problems, which shall be urgently solved in the blast-resistance safety evaluation of dam, are discussed from the field blast test and numerical analysis. Furthermore, the theory and method of the blast-resistance safety evaluation of high dams subjected to different blast attacks are systematically analyzed. The related contents include the blast wave propagation, multi-media transient coupling mechanism, dynamic damage constitutive model at high strain rate, damage effects of dams under different attack scenarios, and blast-resistance performance of different dam types. Finally, the strategic goal and key research direction of blast-resistance research on high dam are put forward.
