K
max
is the maximum acceleration of the sliding mass from the crest to the depth
y
.
K
max
is determined from the abacus in Figure 10.6 depending on the natural period
and the maximum acceleration at the crest
u

.

is the maximum acceleration at the crest obtained from the spectral analysis,
equal to 1.6 times the spectral acceleration for the natural period of the dam
