Study on Dynamic Calculation Method for Pile Supporting Structure with One Layer Prestressed Anchor

Abstract:

A dynamic calculation model of the pile supporting structure with one layer prestressed anchor for the slope is proposed in this paper. The prestressed anchor is regarded as the elastic support of the pile body. According to the theory of one-dimension elastic wave propagation, the interaction between the pile and the soil is obtained. Then the motion equation of the pile-prestressed anchor is established based on the dynamic interaction. The analytical solutions are obtained. In addition the proposed method is applied to a project case to carry out the seismic analysis and design of the pile supporting structure with one layer prestressed anchor. The calculation method provides a theoretical basis for earthquake response analysis and seismic design of the pile supporting structure with one layer prestressed anchor.
