摘要

在这项研究中，我们研究了用光滑粒子流体力学(SPH)方法进行地震反应分析在模拟地震引起的坡体破坏中的适用性。SPH法是一种利用弹塑性本构模型的连续体大变形分析方法，可以分析地震地震动引起的边坡破坏。渐进式边坡破坏是边坡坍塌的一种形式，只有在地震地震动的作用下才会引起边坡的变形。本研究采用SPH方法对边坡模型进行地震反应分析，研究了输入地震运动周期和材料强度对边坡渐进破坏的影响。此外，通过SPH法进行小变形分析，证明了SPH法进行大变形分析在坡体破坏地震反应分析中的有效性。

SPH ANALYSIS OF PROGRESSIVE SLOPE FAILURE INDUCED BY EARTHQUAKE GROUND MOTION

In this study, we investigated the applicability of earthquake response analysis using Smoothed Particle Hydrodynamics (SPH) method for simulating progressive slope failures induced by earthquakes. The SPH method is a large deformation analysis method of a continuous body that utilizes the elasto-plastic constitutive model and is possible to analyze a slope failure induced by earthquake ground motion. A progressive slope failure is a form of slope collapse in which the deformation of the slope is induced only when the earthquake ground motion is in effect. In this study, we investigated the effect of the period of input seismic motion and the material strength on progressive slope failures by carrying out the earthquake response analysis of the slope models by use of the SPH method. Furthermore, by conducting small deformation analysis by SPH method, we showed that large deformation analysis by SPH method is effective in seismic response analysis for progressive slope failure.
