Abstract:

Seismic response analysis of high CFRD under different inputted earthquake waves is studied using a 3-D authentic nonlinear dynamic analysis method. Performances of a dam under site evaluated wave, specification wave, and measured wave, are evaluated and compared, including acceleration and shear stress response, permanent deformation, slope dynamic stability and anti-seismic safety. Among these three types of waves, site evaluated wave produces the strongest response. It is essential to meet the safety requirement in the case of specification wave, while it is often hard to select proper measured wave. This work would be useful for seismic design of high rock-fill dam.
