Impact of the 5.12 Wenchuan Earthquake on Zipingpu Concrete Face Rock-fill Dam and Its Analysis
The 5.12 Wenchuan Earthquake has hit Zipingpu concrete rock-fill dam hard and rendered a maximum permanent settlement of 100 cm and a horizontal displacement of 60 cm to the darn. Such a large permanent deformation due to earthquake has brought about a large area of separation between the concrete face and the cushion layer plane, resulting in an obvi-ous dislocation of the construction joints of the concrete face above the reservoir water level and a crushed damage of the vertical joints of the concrete face. The damage mechanism has been analyzed according to the field investigation. Proposals are also put forward for the fu-ture analytical computation of the earthquake impact on the concrete face rock-fill dam, anti-seism design and the principle of rehabilitation of the Zipingpu concrete rock-fill dam after the quake as well.
