Abstract Due to the complex stress system of prestressed anchor sheet pile wall，a series of fundamental theoretical issues are not solved completely；and its theoretical understanding lags behind its application greatly，especially in the area of aseismic design theory. To make up this gap，a new simplified method，therefore，is proposed based on previous researches. In the method，the influence of earth pressure from cable on cantilever section of pile is considered；and the influence of seismic comprehensive coefficient Cz on stress status of pile shaft is discussed. In addition，large-scale shaking table test is performed to verify the method；and correction suggestion of Cz is proposed. Through comparison of seismic earth pressures and axial forces between calculation and test under different working conditions，it is proven that the new method is feasible. In addition，the method is easy for engineers in seismic design application，as equations involved are easy to solve.

Key words： pile foundations prestressed anchor sheet pile wall aseismic design shaking table test
