- Abstract:
-
The calculation of dynamic response and seismic safety evaluation of a high CFRD on alluvium de-posit subjected to seismic excitation of different transcendental probabilities were carried out,with emphasis onthe seismic response characteristics of dynamic displacement,acceleration,dynamic stresses of face slab andliquefaction of alluvium deposit under strong excitation. The results show that dynamic displacement,accelera-tion,dynamic stresses of face slab and liquefaction degree of alluvium deposit will increase gradually with theincreasing of seismic wave peak ,but the acceleration magnification will decrease.The seismic safety of dam isstill within a normal range even for transcendental probability 2% in 100 years.
