Abstract: This paper is based on a large number of secondary geological disasters induced by the Wenchuan Earthquake. It designs and completes a large-scale shaking table model test of slopes with the scale of 1: 100.It discusses the design of similarity relation and the model, sensor layout, process of model construction as well as the seismic wave loading system. The results show that the model slopes have amplification effect to the input dynamic load. Upward along with the slope surfaces, the PGA amplification coefficients have a rise tendency and some rhythmic. The variation law of rhythmic is affected by the lithology of slopes, combination of structural surface and vibration direction of the dynamic loads. Coefficients of the PGA amplification along surface of slopes are significantly greater for the vibration direction of dynamic load to horizontal(X)than for the direction of dynamic load to vertical(Z),which shows that the dynamic response of slopes is stronger when the vibration direction X.The PGA amplification coefficients in the vertical direction of the slope body are amplified linearly. They in the horizontal direction change in rhythm. The results can help to understand the dynamic response rules of steep stratified rock slopes in the effect of different kinds of dynamic loads, and provide a basis to study the mechanism of deformation and instability of slopes under earthquake and the design of anti-earthquake structure.
