CFRDs are inherently complex, and their dynamic response and seismic damage under seismic action are manifested in various aspects. However, due to the scarcity of seismic damage data and seismic codes specifically tailored for earth and rock dams, the focus remains primarily on three aspects: deformation of the dam body, stability of the dam slopes, and safety of the panels of the seepage control body. It is believed that the deformation of the dam body may influence the overall performance of the dam, while the stability of the dam slopes and the safety of the panels may affect local functionality to some extent. In this section, drawing upon the extensive finite element dynamic calculations and stochastic dynamic response analyses discussed earlier, we utilize the generalized probability density evolution method to establish the relationship between multi-seismic intensity, multiple performance targets, and destruction probability. Initially, we focus on the deformation of the dam body and the safety of the impermeable panel body.
