摘要：
A modified pseudo-dynamic method is introduced in the paper at first, then geometric model of seismic stability on the waterfront rock slope considering the non-linear twin shear criterion is established. Finally the influence factors on the stability of rock slope are analyzed. The conclusions are drawn that the stability of rock slope decreases as the external loading q, rock unit weight , horizontal seismic acceleration coefficient kh and vertical seismic acceleration coefficient kv increases, and it increases as uniaxial compressive strength sigma c, the water depth h1 and parameters of rock mass properties mi and GSI of rocks increases. These conclusions can provide great instruction significance for the future engineering design.
