英文摘要Several post-earthquake investigations have indicated that the slope structure plays a leading role in the stability of rock slopes under dynamic loads. In this paper, the dynamic response of a horizontal layered-structure rock slope under harmonic Sv wave is studied by making use of the Fast Lagrangian Analysis of Continua method (FLAC). The suitability of FLAC for studying wave transmission across rock joints is validated through comparison with analytical solutions. After parametric studies on Sv wave transmission across the horizontal layered-structure rock slope, it is found that the acceleration amplification coefficient eta, which is defined as the ratio of the acceleration at the monitoring point to the value at the toe, wavily increases with an increase of the height along the slope surface. Meanwhile, the fluctuation weakens with normalized joint stiffness K increasing and enhances with normalized joint spacing zeta increasing. The acceleration amplification coefficient of the slope crest eta(crest) does not monotonously increase with the increase of zeta, but decreases with the increase of K. Additionally, eta(crest) is more sensitive to zeta compared to K. From the contour figures, it can also be found that the contour figures of eta take on rhythm, and the effects of on the acceleration amplification coefficient are more obvious compared to the effects on K.
