摘要

结合简化Bishop法，推导了地震作用下边坡的稳定性计算公式，包括拟静力法（pseudo-static method，简称PSM）、经典拟动力法（pseudo-dynamic method，简称PDM）和修正拟动力法（modified pseudo-dynamic method，简称MPDM）。其中，修正拟动力法将土体视为Kelvin-Voigt材料，考虑了土体的黏弹特性和放大特性。在此基础上，对修正拟动力法进行了推广，使剪应力在坡顶、坡面处均为0，符合边坡应力特征。然后，基于Morlet小波分析，以El centro波为研究对象获得了地震波的频谱分布特征。通过提取峰值加速度PGA时刻的卓越频率，提出了一种考虑地震动时频特征的边坡地震稳定性评价方法。最后，将各方法与实例进行了验证。结果表明：拟动力法所需参数较少且意义明确，能够快速、准确地评价边坡地震稳定性，与时程分析方法结果接近。该研究成果可为边坡地震危险性评价、地震滑坡灾害范围分析预测、抗震应急抢险提供理论依据。

Abstract

Based on the simplified Bishop method

formulas for calculating slope seismic stability are derived

which include the pseudo-static method (PSM)

classical pseudo-dynamic method (PDM) and modified pseudo-dynamic method (MPDM). Among these

MPDM treats soil as Kelvin-Voigt material

considering its viscoelastic and amplification characteristics. MPDM is then applied to slope conditions. Subsequently

Morlet wavelet analysis is used to determine the spectral distribution characteristics of seismic waves

with the El Centro wave as the research object. A method for evaluating the seismic stability of slopes is proposed

taking into account the time-frequency characteristics of ground motion by identifying the predominant frequency at the moment of peak ground acceleration (PGA). The effectiveness of this method is validated through illustrative examples. The results show that slope seismic stability can be assessed rapidly and accurately using the pseudo-dynamic method

which requires fewer parameters and provides clear interpretations

closely resembling the results of the time-history analysis method. These research findings establish a theoretical basis for the seismic risk assessment of slopes

the analysis and prediction of the scope of seismic landslide disasters and earthquake emergency response.
