Research ontheDynamicPropertyofCFRD in the Period of WaterStorage

This paper analyses and summarizes the dynamic property and the change of natural vibration character-isic of concrete faced rockfill dams(CFRD)in the period of water storage on the basis of the result of dynamic sitetest.For the first time,the distrbution of hydrodynamic pressure on the face plate is measured.The research of theaseismic property of CFRD is being perfected.
