In recent years,the embedded anti-slide pile is widely used in the slope support due to its specific characteristics and becomes a main slope support form.In static circumstances,the research of embedded anti-slide pile has been relatively mature,but in dynamic circumstances such pile is rarely studied.This paper adopted dynamic strength reduction,using the FLAC software,and proposes a new method of seismic design.Through the comparison of the earthquake effect on pile,it takes a larger value of internal force for the seismic design of pile,and gets the internal force distribution form of pile.Based on a specific slope,the result shows that not only in static circumstances but also in dynamic calculation,the embedded anti-slide pile can meet the requirements for seismic design of the slope,and it provides a new method for the seismic design of slope support.
