Abstract:Research purposes: According to the Bockingham π theorem,the model of the shaking table of pile - type retaining wall was designed for the embankment of one railway in the southwest Chin. By the shaking table test,the analysis of the displacement responses laws of pile - type retaining wall to the earthquake acceleration was made to get the dynamic response laws of the pile under the effect of earthquake and check the anti - seismic effect of reinforcing the high - slope embankment for the purpose of providing the basis for analysis and evaluation of the anti - seismic stability of the pile - type structure of the embankment.
Research conclusions: The horizontal displacement peak of the pile top and the dynamic strain peak of the pile body increased; with the increase of the acceleration. The maximum dynamic stress of the pile appeared in and under the boundary surface. There was a difference in the vibration direction between the upper and the lower boundary surfaces in vibration process. Under the seismic condition,adding the reinforcement could effectively reduce the dynamic effect of soil on the anchor pile. The pile - type retaining wall structure had a good anti - seismic property and met the anti -seismic design demand of the engineering in the high seismic intensity zone.
