| 摘 要： | 根据假定的边坡破坏面的几何形状，以拟静力法的理论框架分析了土工合成材料加筋边坡对数螺旋线破坏模式下的地震稳定性，整个计算过程采用极限分析的动力学理论。推导出的表达式能够容易地计算出地震荷载作用下为阻止边坡破坏所必需的加筋力和屈服加速度系数，可方便地用于Newmark滑块法计算地震导致的永久性位移的参数确定和稳定性分析。

| Abstract: | According to the assumed geometry of the failure surface,the stability of slopes reinforced with geosynthetics was analyzed within the framework of the pseudo-static approach under the seismic loading only for the log-spiral failure mode.Calculations are conducted by applying the kinematic theorem of limit analysis.Each analytical expression in the article is derived that is enable one to conveniently calculate the reinforcement force required to prevent failure and the yield acceleration of slopes subjecte... |
