Abstract Based on the worksite of Yuxi to Mengzi railway which is located on the strong seismic region of 8 degree intensity，the shaking table test was carried out to simulate the dynamic field situation caused by shear wave. The force acting on the pile，the acceleration in the soil and the deformation at pile top of single pile and double row pile retaining structure under different earthquake accelerations are tested. And the comparisons of support effect for the single pile and the double row pile anti-slide structure are analyzed. It shows that distribution of the total earth pressures and the dynamic earth pressures acting on the back of the piles are the same. And the value of single pile is 1.5 to 2 times greater than that of double row pile structure for the same position. Under the same earthquake acceleration，the peaks of acceleration in the soil of single pile structure is greater than that of double row structure，and the settlement of pile top at the low pile of double pile structure is less than that of single pile structure. The support effect of double row pile retaining structure is better than single pile retaining structure on strong seismic region.

Key words： slope engineering strong seismic region shaking table test high slope retaining structure
