Abstract Finite element strength reduction method is widely used in the support of slope under static state，which has been with good economic benefit. But under the earthquake，how to calculate needs research. As to find a reasonable method of calculation，shaking table test and numerical analysis are adopted. Bidirectional Wenchuan Wolong(NE) earthquake wave is input in the test. Through increasing the input amplitude of seismic waves，soil stress，slope displacement and acceleration response of key point before and after pile shaft are monitored；and the dynamic characteristics and failure mechanism of slope under earthquake are studied. At last，numerical simulation is conducted by complete dynamic finite element method. It is demonstrated that numerical simulation results are in accordance with experimental results. The slope failure is induced by composite effect of tension-shear under earthquake. The bearing capacity with piles for seismic resistance is boosted and this research lays a good basis for the seismic design of embedded anti-slide pile.

Key words： slope engineering shaking table test embedded anti-slide pile earthquake failure mechanism tension-shear
