陈厚群 %J 力学与实践 %D 2006 %I %X The engineering background and guiding principals of seismic safety evaluation of concrete large dams in China are presented in this paper. Particularly, the special features and the linear and non-linear analytical methods for seismic responses of high arch dam system are described. The methods of the random seismic response and reliability assessment of concrete large dams are also discussed. Finally, based on the results of dynamic tests of dam concrete with specimen of fully-graded aggregates, the study on the dynamic failure process and mechanism of dam concrete using three-dimensional meso-mechanics analysis checked by computerized X-ray topography technique is briefly reported. %K mechanics problems %K seismic analysis %K random seismic responses %K concrete large dam %K dynamic behaviors of dam concrete
