Abstract:

The shortage of the traditional method to evaluate aseismic stability of the rockfill on the dam’s slope by the maximum horizontal acceleration is analyzed. Then the formula of the overflying safety factor Ks of the pavement plate for slope pavement is put forward synthetically considering the factors of both horizontal and vertical responding acceleration and the slope angle. The stability of the pavement plate on the downstream slope of a concrete faced rockfill dam is analyzed by the proposed method.

Key words: pavement plate, surface discrete unit, maximum responding horizontal acceleration, overflying safety factor, slope stability
