由于预应力锚索桩板墙结构体系受力复杂，目前一系列基础研究问题仍没有解决，理论研究远落后于工程实践，特别是在抗震设计方面。为弥补此空白，在已有研究基础上，提出一套简化抗震设计计算方法，该方法考虑了锚索对悬臂段桩背所受土压力的影响，探讨地震综合影响系数Cz对桩身受力的影响，并通过大型振动台试验验证该计算方法和对Cz提出修正建议。经比较发现，实测各工况下的桩身地震土压力和轴力分布与计算结果接近，说明此方法具有一定的适用性，并且该方法涉及方程简单，求解容易，更易于工程师在抗震设计中应用。

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.
