Key technologies for safety guarantee of reservoir dam

The defects and dangers of reservoir dam and the law of dam failure are systematically explored herein； in which the in-situ experiment and laboratory experiment of dam failure for the highest dam（entity）in the world are described，and then the failure mechanism and failure process of the failure of earth-rockfill dam are revealed. Furthermore，a series of key technologies related to the construction of the reservoir dam safety guarantee system，which are based on the safety assessment of dangerous dam，the strengthening and risk elimination of defective and dangerous reservoir，the non-engineering measures for the risk control of dam，the information monitoring，prediction and pre-warning of dam safety，the dam risk criteria，etc. are systematically expatiated as well. This study achievement enriches the theory of dam failure and improves the dam failure simulation technology，thus can serve the sector management and practice for the safety of reservoir dam in China.
