Abstract
A practical method to calculate a seismic residual displacement of slope exhibiting complicated critical slip surface has not been established. Moreover, only a horizontal component of seismic motion was considered in the design, not vertical component. Therefore, a calculation method to obtain the seismic residual displacement was presented in this paper, and the seismic residual displacement was calculated with various phase differences between horizontal and vertical components of seismic motion. Simple slope models exhibiting circular and plain slip surfaces were used for the verification. Consequently, the seismic residual displacement become larger with certain combination of horizontal and vertical component in seismic motion.
