摘要：
In order to investigate the stability-loss mechanism of a cataclinal rock slope under earthquake loading, the fatigue strength theory was used to investigate the changes of its mechanical properties under the action of the loading. Seismic waves were simplified as elastic waves to generate equivalent static stresses on a structural plane, and a stability-loss criterion about cataclinal rock slope sliding along the structural plane was obtained. Through taking Tangjiashan landsliding in the Wenchuan earthquake as an example, the rationality of the stability-loss criterion was verified. The research result indicates that sliding of a cataclinal rock slope along a structural plane depends mainly on the dip angle and internal friction angle of the structural plane, the wave impedance of rock masses on the both sides of the structural plane and the incident angle of seismic waves, and the transverse wave is the main factor causing the stability-loss of cataclinal rock slopes. To the Tangjiashan landsliding, the most dangerous incident angle is 0° and 10° to the longitudinal wave and 10° and 20° to the transverse wave.
